ANNUAL REPORT 2012 – KEY IT INDICATORS
1. INTRODUCTION
1.1 History
Instituto de Telecomunicações (it) is a private, not-for-profit organisation, an association of
eight institutions with research and development in the field of Telecommunications:
• Instituto Superior Técnico (IST);
• Universidade de Aveiro (UA);
• Universidade de Coimbra (UC);
• Portugal Telecom Inovação, (PTIn)
• Nokia Siemens Networks S.A
• Universidade da Beira Interior (UBI)
• Universidade do Porto (UP)
• ISCTE - Instituto Universitário de Lisboa (ISCTE-IUL).
it is organised around three sites:
• Aveiro, in the University Campus,
• Coimbra, in Site II of the University of Coimbra,
• Lisbon, in Instituto Superior Técnico,
and four branches:
• Leiria, in the “Escola Superior de Tecnologia e Gestão” of the Leiria Polytechnic (IPL),
• Covilhã, in the University of Beira Interior (UBI),
• Porto, shared by the Faculty of Engineering (FEUP) and the Faculty of Sciences of the
University of Porto (FCUP),
• Lisboa, in ISCTE - Instituto Universitário de Lisboa (ISCTE-IUL).
Setting up of it was the result of a 1.5 billion escudos (about 7.5 million Euros) grant from
Programme CIENCIA, through three contracts signed in 1991. This investment enabled new
infrastructures to be built and research laboratories to be equipped at each site.
Installation was concluded in Aveiro in 1993 and in Lisbon and Coimbra in 1994. Since 1993, it
activities proceed regularly.
it bylaws were first approved in 1992, modified in 1997, 2003 and 2011. New Site bylaws
deriving from it bylaws were approved and implemented in 2011.

Key developments in 2012 are highlighted ahead. Details are included in the sections dealing
with each of the research areas.
1.2 Management
it is managed by a Board of Directors, elected by the General Assembly, and by Site
Management Boards, which include the Site members of the Board of Directors. Site
Management Boards enjoy ample freedom to deal with current affairs and usually meet
weekly. The Board of Directors meets at least once a month.
it scientific activities are overseen by the Scientific Board, which includes all it researchers
holding a Ph.D. degree. The Scientific Board meets in Plenary or in Committees, both
permanent and temporary. There are two permanent committees: the Science and Technology
Committee and the Research Group Coordination Committee.
it Work Plan and the Annual Report are discussed with the Advisory Committee, formed by
three independent experts in the field of telecommunications (Dr. Roland Huber, Prof. Sir John
O’Reilly and Prof. Martin Tomlinson) acting in a personal capacity, and together with the
Accounts Report (after legal certification) are subsequently submitted to the General Assembly
for approval.
The General Assembly met formally twice in 2012. The first meeting was held on July 27th, in
the Meeting Room of the Lisbon site, to discuss and approve the 2011 Annual Report and
Accounts, to analyse the membership request from Instituto Politécnico de Leiria, Instituto
Superior de Engenharia de Lisboa and the Universidade do Algarve, to discuss the possibility of
opening delegations at the Instituto Superior de Engenharia de Lisboa and the Universidade do
Algarve and to elect the members of the Board of Directors for the period 2012 - 2014. The
second meeting took place on December 12th, in the Meeting Room of the Rectorate of
Universidade da Beira Interior, to discuss and approve the Work Plan and Budget for 2013.
The Research Group Coordination Committee also met twice during 2012. On the first meeting,
held on March 20th, at it auditorium at the Aveiro site, the Draft Proposal of the 2011 Annual
Report and the proposals for opening delegations at Instituto Superior de Engenharia de Lisboa
and the Universidade do Algarve were discussed and received a favourable opinion. On the
second meeting, held on December 17th, in meeting room 2 of IST Congress Center Hotel
(Coimbra), the Work Plan and Budget for 2012 were discussed and received a favourable
10
opinion. The first year reports of the first batch of internal projects were presented and
discussed.
The Advisory Board visited it (Lisbon, Coimbra, Aveiro and Porto) on the 11th and 12th of
January 2012. Researchers from Covilhã and Leiria were interviewed in Coimbra. The report
(included in Annex) is highly positive in what regards it scientific achievements and
recommends more focus on technology transfer.
1.3 Highlights of 2012
Scientific output
In spite of the very serious reduction of funding, mainly from FCT strategic funding, it scientific
output in 2012 reached an all time high (the apparent contradiction of scientific output
increase versus reduction of funding is explained ahead):
• 25 books;
• 53 book chapters;
• 335 papers in international refereed scientific journals;
• 479 papers in refereed conferences, with published proceedings;
• 9 patent filed.
Foreseen output for 2012 was
• 30 books and book chapters;
• 200 papers in international refereed scientific journals;
• 400 papers in refereed conferences, with published proceedings.
Achieved scientific output exceeded by far our forecast, in all areas, and became a new record.
Fostering advanced education also reached an all time high:
• 42 PhD theses, submitted and approved,
• 207 MSc theses, submitted and approved,
where the estimated numbers for 2012 were:
• 30 PhD theses, submitted and approved,
• 200 MSc theses, submitted and approved.
11
It is worth noting that, for the first time, the number of concluded PhD theses approaches one
fourth of the number of PhD students, that is, the duration of the thesis work approaches four
years.

The number of scholarships decreased significantly in 2012 with respect to 2011, due to a
largely reduced FCT strategic funding (as explained in more detail below), that is:
•
181 Ph.D. scholarships, funded by FCT;
13
•
209 other scholarships, funded by it, as follows:
• 32 Ph.D scholarships
• 45 B.Sc. scholarships
• 75 M.Sc. scholarships
• 24 post-PhD scholarships
• 1 technician scholarship
• 4 Integration in R&D fellowships,
• 21 R&D starting grants
• 2 Management of Science and Technology fellowships,
• 5 mobility fellowships associated with the CMU-Portugal Program.
During 2012, 140 nationally funded and 29 internationally funded projects were active, as
shown in section 2.2. It is particularly noteworthy the fact that on the 31st of December it was
involved in 21 running FP7 projects (running and selected for funding) in addition to other 3
projects, where there was involvement of some it researchers from the Lisbon site.
IT funding
In the past few years, FCT strategic funding i.e. funding for the IT - Laboratório Associado
contract, was never timely. It suffices to say that funding for 2010, about 2.2 M€, was
received in January 2011 and was executed (98 % rate) until December 31st 2011.
Strategic funding for 2011-2012 obeyed new rules: an upfront payment of 20 % of the
approved budget (ie 1.2 M€), followed by the reimbursement of 80 % of the accepted
expenses. The 20 % share was received in two instalments (April and August 2011) but its
executing only started in January 2012, since during 2011 it was running with the 2010
strategic funding. In part, this was the reason for the observed low impact in 2012 of the
funding shortage on it’s scientific output.
As foreseen right in October 2011, this new payment method was extremely damaging
because FCT was never able to process reimbursements in less than three months. In addition
the number of payment requests increased dramatically from once a year up to twenty or
more (for the IT – Laboratório Associado contract). In fact, the delay in reimbursements
exceeded our worse expectations. Not only it reached (in cases) up to 6 months but, worse
14
still, many expenses were deemed to be non eligible on the first submission, forcing it to
resubmit again and again the same expenses, with renewed justifications.
At the time of writing, it has executed the whole advanced payment and submitted claims for
1011 k€ and received 247 k€ (instead of 809 k€). The remaining claims should be submitted
until March 31st 2013 but it is still unclear if the remaining reimbursements will ever be made.
Since about 50% of the reimbursements were paid in December 24th, 2012, it was not
feasible to use these sums for payments in 2012. FCT demanded that 2011-2012 funding
should be used until December 31st 2012, contrary to previous practice and general
expectations, delivered a very serious blow to strategic funding.
At present it is unclear if reimbursements, both paid late and due but not paid in 2012 may be
used for eligible expenses during 2013.
To compound things, in July 2012 FCT took the unilateral decision that mission grants could no
longer be accepted as eligible, even if these grants are defined in it grant regulation approved
by FCT. This decision of non-eligibility of already made mission expenses, (because in this
instance FCT had made up 90% advance payments), prevented these projects from closing
and thus prevented it from getting the final payment (10%). Finally in November 2012, FCT
agreed to accept eligibility of mission grant expenses up to December 31st 2012 subject to
some minor changes in the submission of such expenses. New rules and procedures will apply
from January 2013 onwards, for mission funding.
To complete the bleak picture, it should be mentioned that from August 12th, 2012, it must
comply with the rules of the Code of Public Contracts. The resulting increased bureaucracy is
appalling to say the least and already has negative impact in it activity, not to mention the
increase in administrative staff and bureaucratic costs.
From the above it is quite clear that it management was cautious and did not embark in
borrowing money to execute the contract value (3 M€ for 2012) since FCT never guarantied
that reimbursements were to be paid. This cautious approach earned it a serious (40%)
decrease in 2013 strategic funding, which was (up to now) calculated on the basis of the
amounts executed in 2012.

it is a member of the CIENCIA VIVA, the National Agency for Scientific and Technological
culture and co-operates in some of its events, namely those related with the diffusion of
know-how on electromagnetic radiation and its effects on the human body. Project MONIT,
(www.lx.it.pt/monit) was actively engaged in promoting and diffusing know how on
electromagnetic radiation and mobile communications. Occasionally, through this project, it
offers two week training in the measurement of electromagnetic radiation.
Sponsored by CIENCIA VIVA, it organized a one-week hands-on introductory course on
telecommunications for 10th and 11th grade high school pupils with 15 enthusiastic
participants and an open-lab two hour session for a similar audience.
Also in cooperation with IST, it organized visits and demonstrations for high school pupils,
involving about 1000 pupils (in 2012).
During 2012, it commemorated its 20th aniversary with half-day seminars, visits,
exhibitions and demonstrations in its 3 sites and 4 delegations, which all in all joined more
than 600 participants.
During 2012 it reinitiated a regular publication of its monthly newsletter, which is
distributed electronically to all researchers and PhD students and also started to be present
in social networks (Facebook, YouTube and Flickr).
Finally it should be stressed that in 2012 it researchers created two new companies
(Veniam, Streambolic). Streambolic earned the grand prize at the 8th BES Concurso
Nacional de Inovação and Veniam won the 3rd Building Global Innovators Venture
Competition ISCTE-IUL MIT.

2. KEY IT INDICATORS
Human Resources
In December 2012 it human resources included 720 people distributed as follows:
• 262 researchers;
• 223 PhD students;
• 206 grantees;
• 12 technical;
• 17 administrative.
All researchers but 2, hold a PhD degree.
The distribution of all human resources between the three sites is represented graphically in
Figure 2.1. It is obvious from this figure that the ratios between PhD students and
researchers and between grantees and researchers is much higher in Aveiro than in Lisbon
a fact that is partly explained by the much higher involvement of Aveiro in FP7 projects.
20
Figure 2.1: Distribution of it human resources between the three sites
The distribution of researchers and PhD students between sites and delegations is shown in
Figure 2.2.
This figure shows, more than the previous one, the lower proportion of PhD
students in relation to the number of researchers in the IST site and, even more seriously,
in the ISCTE branch.
21
Figure 2.2: Distribution of itresearchers and PhD students
among associated universities
Unfortunately our accounting systems only provides site information for grantees and thus it
is not yet possible to have a more detailed picture of grantees distribution.
As a result of the application it quality policy, out from the 260 researchers holding a PhD
Degree, 50 were excluded from FCT basic funding, and 12 had a 25 % reduction of FCT
basic funding. As a result, in the first semester of 2012 it has 191.25 eligible researchers.
The distribution of it technical and administrative staff is shown on Figure 2.3 and 2.4.

The scientific productivity in 2012 was 1.75 journal papers per eligible researcher or,
counting each book, bookchapter and journal paper as one publication, 2.15 publications
per eligible researcher.
It is interesting to compare in Fig 2.5 to Fig. 2.11 the distribution of the number of
researchers per site and delegation with the number of number of published works (papers
in international journals and communications to refereed conferences). One should note
that in these graphics the sum of the number of publications per site and/or delegation is
higher than the number of publications for it because a significant number of publications
(about 30%) are authored by researchers from more than one site and/or delegation. This
fact in itself is an important indicator that it is increasingly operating as a unity rather than
as a collection of research units. In the following figures, it and CIENCIA paid researchers
and their publications are not included.

Even if Figures 2.7 to 2.14 are self explanatory, it is interesting to remark that at the level
of papers in journals, site distribution follows very closely research distribution. Differences
are slight at the level of communications to conferences and considerable at the number of
patents where the importance of Porto shines. Going into delegations, some differences are
rather more striking, particularly at the level of papers in journals, which could not be seen
at the site level.
Networks and Sinergies
it management has been trying hard to improve networking not only between its
researchers but also with external researchers. Using social network analysis software tool
(NodeXL) and it databse of journal publications in 2012 with kwnon ISI WoS impact factor,
figure 2.13 was produced representing it co-authorship network in 2012.
In this figure each researcher is represented by a disk whose colour indicates the researcher
scientific aera according to the following code:
•
Red – Wireless Communications,
•
Blue – Optical Communicatons,
•
Orange – Networks and Multimedia,
•
Green – Basic Science and Enabling Technologies.
The disk diameter is proporcional to the member of connections originated by each mode. The
existence of a paper authored by two or more researchers is represented by a line between the
modes involved. The networking strength in 2012 is apparent in figure 2.13 and may be better
appreciated in figure 2.14 that was obtained using it database of ISI journal papers for the
period 2007 to 2011. Although most connections involve researchers of the same scientific
area, there is a significant number of connections between researchers of different scientific
areas, a clear indicator of the synergies it is fostering. Connections with external authors are
not shown for coarity.
In both figures the small disks shown at the bottom left represent authors with 2 or less
connections.

4.1.3.2
Antenna Analysis and Design
Work on antennas has been focused on a few main topics: antennas
for RFID and UWB systems and antennas for microwave and mm-wave
applications
with
emphasis
on
antennas
for
Ka-band
satellite
communications and small antennas for indoor applications.
4.1.3.3
RFID and UWB Antenas
Work continued on the design of UHF RFID tag antennas and UWB
antennas
for
indoor
personal
communications
and
for
indoor
localization. New low-cost antennas for UWB indoor localization,
including
hybrid
antennas
appropriate
for
simultaneous
RFID
identification and UWB localization have been designed. A system
demonstrator and new algorithms for indoor localization enhancement
were developed.
Work continued also on near-field reader antennas for UHF-RFID
confined detection applications, including mirror embedded transparent
antennas.
Low cost UHF RFID tag antennas for near-body applications, including
interworking with body-implantable antennas have been designed,
fabricated
and
experimentally
tested.
Emerging
low-cost
tag
fabrication techniques based on ink-jet printed have been explored.
A source-stirred UWB radiation efficiency measurement method was
developed and results were compared with reverberation chamber
measurements and computer simulations. The method provided a
simple
cavity-based
approach
to
UWB
antenna
efficiency
measurement.
An efficient and simple UWB model of a human limb was introduced for
antenna simulations. The adequacy of the model was confirmed by
antenna measurements and an antenna prototype for wearable
systems was developed.
UWB matching resilience of dielectric loaded antennas was confirmed
and improved through measurements and by using a simple and
accurate human limb model.
4.1.3.4
Satellite related antennas
• Development of
a new concept of low-cost antenna for GPS-based
positioning calibration for precision demanding applications
like
aircraft instrument landing systems in airports;
• New
developments
on low-cost
dielectric lens-based
mechanical
steerable beam antenna for Ka ground terminal satellite services;
• Design of multi-beam metamaterial-based Fabry-Perot antennas for Ka
satellite deck installation;
Design and test of microstrip patch antenna elements and arrays for
Ka band space applications;
4.1.3.5
Other antenna related topics
Other lines of research have been pursued including:
• Design and test of an implantable compact antenna to be applied
under the human skin for medical applications;
• Work was also put in the designing of special antenna structures for
vehicular communications, among vehicles and between vehicles and
infrastructures based on wireless communication technology known as
dedicated short range communications (DSRC). DSRC are in great
development with the aim of reducing traffic problems and improving
road safety. The study addressed both the development of an antenna
solution for the mobile module, usually named On-Board Unit (OBU)
and the design of an antenna for the RSU (Road Side Unit).
4.1.3.6
Circuits and systems for wireless communications
During 2012 the work devoted to wireless circuits and systems was
mainly concentrated in the design of flexible radio circuits and systems
for several applications, including: Software Defined Radio systems,
Wireless Power Transmission, Nonlinear Models and Characterization
for high speed digital buffers, Circuits for Dedicated Short Range
Communications.
4.1.3.7
New
Agile Transmitters
reconfigurable ΣΔ-based
transmitter
architecture
supporting
multichannel multimode data transmission has been designed and
validated. The high flexibility of this architecture enables a data
transmission scenario where the frequencies of the carriers and the
spectral masks can be easily changed through software, making this
agile
transmitter
applications.
interesting
for
use
in
cognitive
radio-based
Moreover injection locked class-E power amplifiers were built and
characterized in CMOS technologies. The prototypes achieved almost
30 dBm output power. An EER amplifier was designed and built. An
envelope detector and a DC-DC converter were included in the
architecture. The converter filter is off-chip but the rest of the system
is fully integrated.
Monolithic power combiners are being studied and designed. These
structures will be integrated with the power amplifiers. A TLT and LC
baluns and Wilkinson combiners were submitted to fabrication in CMOS
technology.
An effort was made with the internationalization. Research cooperation
with State Key Laboratory from Macau University has also started in
this field. The challenge to use new CMOS technologies with 130, 90
and 65nm channel length was achieved. Also an important investment
was made in using electromagnetic and systemic simulators.
Highly efficient wireless transmitter architectures based on a pulsed
operation were also addressed this year in complementing agile
transmitters. In that sense the study of the viability of building highly
efficient and linear carrier-burst transmitters, namely to study their
practical implementation difficulties was addressed. Beyond these
works, research was carried on the design of nonlinear behavioral
models for telecommunication sub-systems and devices, and their use
in digital pre-distortion linearization. The application of these studies
has been directed to both conventional Cartesian and polar wireless
transmitters, namely for current-mode and switched-mode RF power
amplifiers and wireless transmitter systems.
Some extra works on a buck switch mode converter at 100MHz was
fabricated and tested in a 180nm CMOS, to supply a Class-D PA. A 5V
to 1.8V buck converter at 100MHz was also designed and sent for
fabrication, using a cascode topology for the power circuit switches, in
a 180nm CMOS. The study and design of a fully integrated buck switch
mode converter was started. The idea is the increase in switching
frequencies up to hundreds of MHz (>300), in order to integrate the LC
filter. Preliminary results indicate the viability of the proposal.
A strong effort was put on the study of its nonlinear impairments to the
overall
linearity
and
efficiency.
Other
technologies
have
been
approached as self-oscillating power amplifiers that constitute an
innovative architecture that has theoretical 100% efficient operation
under linear operation. The end of this year also marked the beginning
of a research project in collaboration with an International Company
aiming to study distortion generation mechanisms in Doherty power
amplifiers.
4.1.3.8
Agile Receivers
This year some innovative ideas for increased dynamic range and
bandwidth for software defined radio receivers were also explored,
including the study of nonlinear behaviors, which is fundamental for
the increase of the dynamic range.
This was complemented with theoretical evaluation of polynomial
behavioral model simplifications using circuit level physical knowledge
and general Volterra series calculations, and also combined with the
study of Predistortion theoretical limits. The goal of this work is to
calculate the maximum power efficiency of an amplifier with and
without the use of a predistorter in order to determine the maximum
profit that can be obtained using this technique.
Study of low noise amplifiers was also pursued this year by designing a
simple version of a SiGe active inductor with less transistors and
independent voltage control of inductance and quality factor. A 30GHz
LNA with CMOS technology was designed and sent for fabrication.
4.1.3.9
Dedicated Short Range Communications Systems
Work was focused on the development of Proof of Concept on wireless
communications system for road applications, with emphasis on safety,
following the WAVE recommendation”. While the standard IEEE802.11.p is not completed, the development followed the IEEE
802.11.a
whenever
necessary.
Following
the
current
802.11p
recommendations, basic functionalities were implemented in order to
comply with the identified applications and scenarios.
Some extra work was also put in this activities for designing special
antenna structures for Vehicular communications, among vehicles and
between

of reduce the traffic problems and improve the road safety. One study
was based on the development of a solution to an antenna to be used
in the mobile module, usually named On-Board Unit (OBU). Another
possibility was the design of an antenna for the RSU (Road Side Unit).
4.1.3.10
Design, Measurement and Characterization of CMOS
and BICMOS SIGE RF Circuits

reconfigurability and the base-station transmitter bandwidth.
• Two different architectures were studied for the mobile wireless
transmitter. One was the self-oscillating power amplifier or limit-cycle
amplifier where several system level studies were conducted, both at
RF and baseband, of limit cycle loops and appropriate modulation
formats. In terms of hardware development, a special attention was
paid to the development of dynamic negative hysteresis switches for
reduced switching noise.
• The second architecture was the carrier amplitude-burst transmitter
in which several detailed studies were conducted on its efficiency and
linearity limitations. The proposed models were validated through the
measurement of a specially designed transmitter prototype.
• For the base-station transmitter, the focus was on the Doherty
arrangement (and its associated digital pre-distortion), namely on
understanding the physical mechanisms responsible for the nonlinear
distortion that arises on the carrier and peaking PAs and then on the
complete 2-way Doherty PA.
• Most of this work was funded by the FCT Project SOPAS.

digital pre-distortion technologies (measurement benches and DSP
techniques) capable of achieving more than 60dB of intermodulation
ratio.
• This

4.1.3.13
Signal Integrity Analysis in Mixed-Signal IC Devices
• The aim of this research topic was to develop accurate behavioral
models for the efficient simulation of wireless circuits incorporating
digital and mixed-signal high-speed devices. A new behavioral model
for an input-output buffer/driver was developed and tested under
signal integrity analysis applications. This model is based on the
decomposition of the observed voltage-driven current on its conductive
and displacement components, as previously adopted in the in-phase
and quadrature models of nonlinear RF devices. Also, a dedicated
method was conceived to extract this model from digital IC transient
simulations and a measurement set-up was developed and tested to be
able to replicate the required extraction procedure in a RF laboratory.
4.1.3.14
Numerical Techniques for Circuit/System Simulation
• Considering the heterogeneity of self-oscillating power amplifiers,
especially in terms of their strongly nonlinear operating regimes of
operation, and also the existence of widely separated scales, a generic
and comprehensive study of all computational simulation tools that
operate strictly in the time domain was conducted. The main
characteristics of these algorithms were analyzed, and a comparative
study in terms of their efficiency was performed. Then, to circumvent
the problem of numerical "stiffness" in RF circuit simulation, an
innovative computational tool was designed and implemented. The
computational tool developed in this context was specially designed for
strongly nonlinear circuits operating on a fast time scale and two
slower time scales, and resulted from a combination of advanced
multirate simulation techniques, such as the method of lines based on
multirate Runge-Kutta schemes and time-domain envelope following
techniques, such as "envelope transient over shooting". Performance
tests conducted on a RF polar power amplifier revealed very promising
results in terms of computational efficiency.
4.1.3.15
Circuit Theory and Power Supplies
• Optimization of power flow on transmission lines for sustainable
energy systems is under study; a new process for reducing the power
losses was developed and tested on a real scenario.
• The study and design of a fully integrated buck switch mode
converter was completed. The converter includes an integrated
inductor of 15nH at a switching frequency of 300 MHz. The block was
tested for both static and dynamic supply of a switch mode class-D RFPA. Extracted results in a 180nm CMOS process indicate the viability of
the proposal.
4.1.3.16
Wireless Power Transmission
This year a new area emerged on the design of better and improved
circuits for wireless power transmission: the effort was put on the
design of RF-DC converters and on the design of highly efficient
waveforms for maximizing the range of these circuits.
4.1.3.17
Waves and Propagation
Work in this sub-area focused on the effects of vegetation media on
the propagation of radiowaves, RF measurement systems at microand millimeter wave frequencies, propagation through building walls as
well as fundamental research on electromagnetics of complex media
with possible applications to antennas and guided wave structures.
Studies on EM exposure assessment have also been pursued.

Radiowave Propagation Modelling
• Optimization of a versatile radio channel sounder prototype with the
capability
of
characterizing
doubly
selective
channels
through
measurements of key channel indicators, e.g. Doppler spectra, channel
impulse response (with time resolution better than 2 ns) and
coherence time at 18, 37 and 61 GHz. Such development of a multifrequency swept-time delay cross-correlation channel sounder for
propagation studies allowed building upon the doubly selective channel
models widely available in the literature, so that refined and new
models incorporating both channel time varying and multipath effects.
This was accomplished through appropriate measurements of the radio
channel for various geometries and frequencies.
• Progress was made in the development of a ray tracing based
simulation platform for realistic doubly selective radio channels, with
MIMO capabilities, including vegetation media. This framework in its
present stage is the integration of various propagation models present
in literature, with a novel method of characterize the obstacles
presented in the radio path, specifically for vegetation specimens,
yielding only to point scatterers with specific characteristics, which
allows a great variety of obstacles. This allows one to extract various
parameters of the channel under simulation, such as, the received
signal complex envelope, Doppler spread and power delay profile
(PDP).
• Progress was made on the development of a novel time-varying
radiowave model in vegetation media at micro- and millimeter-wave
frequencies. The model is based on the discrete (Radiative Energy
Transfer) theory extended to include channel dynamics, for various
vegetation species and frequencies.

Future wireless systems should fulfill several goals, among which: provision
of true broadband wireless access and enhanced system capacity when
compared with current 3rd Generation (3G) networks. Obviously, to achieve
a generalized deployment all the technical solutions are constrained by the

Advanced Code and Receiver Designs for Transmission over Selective
Radio C
Funding
FCT/PTDC
Descript.
Future wireless systems are expected to support data rates of several
hundreds of Mbit/s in a variety of scenarios with high spectral and
power efficiencies. Due to high transmission rates the channel will be
severely time dispersive. For this reason, block transmission techniques
combined
with
frequency-domain
equalization
(such
as,
OFDM
(Orthogonal Frequency Division Multiplexing) and SC-FDE (SingleCarrier Frequency-Domain Equalization) modulations schemes are
strongly recommendable.
A key technology to improve power and spectral efficiencies is the use
of multi-antenna schemes exploiting spatial diversity (such as STF
(Space-Time-Frequency) codes) and spatial multiplexing (such as LST
(Layered Space-Time) techniques). The use of signals with reduced
envelope fluctuations is also important to allow efficient power
amplification. This is particularly important in the case of OFDM signals.
Conventional FDE implementations require accurate channel estimates
at the receiver, something particularly important in multi-antennas
systems. These estimates can be obtained with the help of appropriate
training symbols or blocks. Due to frequency offsets and Doppler
effects, the channel is expected to change from block to block, or even
within a given block, especially for large blocks, high carrier frequencies
and/or high moving speeds. In this case, it might be recommendable to
employ
non-coherent
systems.
This
project
considers
efficient
transmission schemes for frequency-selective channels. For this reason,
we will employ OFDM and SC-FDE block transmission formats with
multi-antenna schemes. The research team involved in this project
includes researchers working in transmission, codebook and receiver
design and optimization, as well as researchers working on propagation
issues. In the first phase of this project, we address the problem of STF
codebook design for both coherent and non-coherent communications.
In contrast with conventional approaches, the codebook design takes
into account the envelope fluctuations and dynamic range of the
transmitted signals, so as to allow efficient power amplification. We will
also take into account non-linear effects (e.g., due to clipping of OFDM
signals) in the STF code design. The impact of nonlinear distortion
effects on the designed STF codes will be studied, whenever possible,
employing analytical methods. Contrarily to the usual approach, we will
take into account non-white noise effects (e.g., due to self-distortion
inherent to nonlinear effects) in our designs. Pragmatic code designs
(eventually combined with conventional error correction schemes and
allowing low-complexity transmitter/receiver implementations) will also
be considered. In the second phase of this project, we will generalize
the results obtained in the first phase to the fading channels that are
both time-dispersive and time varying (i.e., doubly selective channels).
For the coherent case, the combination of suitable block/frame designs
and adequate estimation and tracking techniques (both for the channel
frequency response and the frequency offsets/phase noise carrier) will
be considered to cope with time-varying channels. We will also develop
receiver structures for the case where the channel changes significantly
within
a
given
block,
both
coherent
and
non-coherent.
To achieve these goals, we need accurate channel models taking into
account short-term and long-term variations. We will develop new,
more
accurate
narrow
and
wideband
channel
models
through
theoretical investigations as well as experimental data gathering for
different frequencies (e.g., 2.4, 5.6 and 38 GHz), in several deployment
scenarios. A time-varying tapped delay line based model will be
developed to represent the doubly selective channel phenomena. The

Descript.
• The aim of the project is to provide a better understanding of multiuser
coordinated
multiple-input-multiple-output
(MIMO)
capacity
enhancement in the fourth (and future) generation(s) of wireless
systems.
In
fact,
the
realistic
capacity
estimation
using
spatial
multiplexing and beamforming MIMO is of great interest, since it
represents the enabling technology to achieve the new 4G 5 bit/s/Hz
spectral efficiency requirement.
• MIMO links can offer a so called spatial multiplexing gain by opening
parallel spatial data pipes or channels within the same frequency band.
This is achieved by the creation of orthogonal information channels
mostly
in
the
presence
of
rich
multipath
leading
to
antenna
decorrelation.
In these conditions, MIMO links offer capacity gains (relatively to SISO)
that are proportional to the minimum of either the number of TX and RX
antennas. As a matter of fact, a key feature of MIMO is to turn multipath
propagation, traditionally a pitfall of wireless systems into a benefit for
the user. MIMO takes advantage of random fading, for increasing
transfer rates.
• The proposed work in the project will cross the fields of research of
mobility and channel modeling, information theory and practical systems
and applications. Firstly, directional channel modeling will be developed
in order to simulate the MIMO channel.
• Secondly, information theory and eigenanalysis based on MIMO spatial
multiplexing and beamforming will be used, together with the use of
uniform and power efficient allocation methods. Optimized MIMO
antenna configurations will be set, in order to boost up cell capacity.
Then, the gains of using coordination methods in multiuser scenarios will
be considered with applications examples and system performance
evaluations over LTE (and LTE Advanced) and mobile WiMAX 802.16
family of standards radio interfaces.
• This evaluation will be done considering radio advanced resource
management techniques such as improved admission control, power
control and scheduling techniques.

Heterogeneous Wireless Networks
Funding
Descript.
ESF, COST
The main objective of the COST Action IC0902 is to integrate the
cognitive concept across all layers of communication systems, resulting
in the definition of a European platform for cognitive radio and
networks.
The Action proposes coordinated research in the field of cognitive radio
and networks. The cognitive concept applies to coexistence between
heterogeneous wireless networks, that
share the
electromagnetic
spectrum for maximum efficiency in resource management. Several
efforts are currently in place in European research centers and consortia
to
introduce
cognitive
mechanisms
at
different
layers
of
the
communications protocol stack. This Action goes beyond the above
trend by integrating the cognitive concept across all layers of system
architecture, in view of joint optimization of link adaptation based on
spectrum sensing , resource allocation, and selection between multiple
networks, including underlay technologies.
The cross-layer approach will provide a new perspective in the design of
cognitive
systems,
based
on
a
global
optimization
process
that
integrates existing cognitive radio projects, thanks to the merge of a
wide-range of expertise, from hardware to applications, provided by
over 30 academic and industrial partners.
The final result will be the definition of a European platform for cognitive
radio and networks. To reach this goal, algorithms and protocols for all
layers of the communications stack will be designed, and a set of
standard interfaces as well as a common reference language for
interaction between cognitive network nodes will be defined.

The project main goal is to turn a waste produced by oil industry in a byproduct for cement industry. This synergy will generate significant
economic and environmental dividends for both the oil and cement
industries as they become more technologically advanced. Despite the
great benefits of incorporating the waste from Fluid Catalytic Cracking
(FCC) unit into cement-based materials, there is still an extensive lack of
fundamental understanding about the reaction mechanisms, as well the
microstructure of the blended materials. The project addresses to
integrate various types of analysis done at the nano and microscale, and
correlate these analyses with the mechanical properties of the blended
cement materials. The fundamental knowledge generated will contribute
to improve the industrial formulation of FCC catalyst/cement blended
materials. Progress in this domain can be considered a breakthrough in
an
efficient

of
this
waste.
IT role will be:
- Development of novel signal and image processing techniques for data
acquired via electronic microscopy;

The large number of foreseen devices coupled with the surge in power
requirements for future emerging handsets raises significant challenges
in terms of: i) reducing the energy consumption; and ii) reducing the
amount of electromagnetic radiations. GREENET targets the following
main objectives:
1. Recruitment of ESRs with the clear and long-term objective to conduct
top-notch research and to pursue research excellence at the national,
European, and international levels.
2. Develop training and career plans that are personalized as possible to
meet the needs and desires of each ESR.
3. To allow the ESRs to understand and address key research challenges
on energy efficient GREENET communications, that form pivotal societal
and economic concerns for Europe within the mid-to-long term.
4. Offer to each ESR top-level training and research programs with the
twofold objective to reinforce and corroborate their own background, as
well as to complement this with active participation in a multidisciplinary network of research scientists.
5. Complement the typical competences of “applied research” with
aspects related to project management, intellectual property rights,
writing of patents, presentation and communication skills, writing of
technical papers, exploitation of technical results and creation of start-up
companies, etc.

Multi-Packet Detection Techniques for Satellite Networks
Funding
FCT/PTDC
Descript.
Future satellite communications systems face a challenge to provide
higher bitrates, together with improved QoS (quality of service)
guarantees, to more GT (ground terminals). Moreover, this should be
achieved with higher spectral and power efficiencies, with less energy.
This project considers future very high bitrate LEO (Low Earth Orbit)
satellite systems with satellite MPR (multipacket reception), compatible
with low-cost portable GTs. A cross-layered approach is proposed: a
physical layer team will handle the signal design, the synchronization
and
estimation
issues,
and
the
receiver
design,
including
MPR
development; a data link layer team will handle the Multiple Access
control protocol design and the scheduling algorithm to support different
QoS (Quality of Service) classes, and the interaction with the network
layers. Both teams will be involved in the design and test of the crosslayering features involving both layers, required to provide guaranteed
QoS,
even
during
satellite
handover.
In this project we will develop OQPSK-type schemes with reduced
envelope fluctuations and high power and spectral efficiencies and
compatible with an efficient and low cost power amplification. To further
improve the overall system power efficiency we also consider schemes
with spectral overlapping between different frequency channels. With
respect to the receiver design, the main goal is an efficient multipacket
detection technique able to cope with collisions, already shown by the
research team to allow significant improvements in personal area
networks. We will consider turbo frequency-domain equalizers suitable to
cope with time-dispersion effects and able to handle spectral overlapping
between
frequency
channels.
Hybrid
ARQ/FEC
(Automatic
Repeat
reQuest/Forward Error Correction), namely with packet combining, will
be proposed to handle fading for the most demanding QoS classes and
control packets. To cope with Doppler effects, suitable synchronization
and channel estimation methods will be developed for MPR on a LEO
scenario. Joint detection and estimation schemes will be considered.
Since MPR needs to know which users are involved in a collision, suitable
methods
to
detect
them
will
be
developed.
The
statistical
characterization of block error rates with MPR will be evaluated using
simulations for homogenous and heterogeneous SNR GTs. We will
develop a new MAC protocols for MPR that combine random access with
demand assigned access on the uplink controlled by a downlink control
channel, offering improved QoS support compared to other LEO MAC
protocols.

LTE-Advanced Enhancements using Femtocells
Funding
FCT/PTDC
Descript.
-
The project will take LTE-Advanced as a reference and will explore
possible enhancements to the support of femtocells. It will use
mechanisms to reduce the interference-limited transmission with full
frequency reuse. These include CQI, QoS- and interference- aware
scheduling and RRM with user-grouping, coordinated RRM, exploiting
the spatial degrees of freedoms from multi-antenna systems and
OFDMA
through
MIMO
and
beam

techniques,
active
interference management and CoMP transmission, as well as carrier
aggregation
for
multi-band
transmission.
New
technologies
like
aggregate carriers and cooperative multi antennas antenna systems as
part of LTE-Advanced systems will be evaluated with respect to their
ability to enhance the performance of networked femtocells based on
LTE-A. The availability of Positioning information, can help provide the
network with information on the terminal positions and, with this, to
adapt the transmission scheme to the terminal avoiding worst channel
conditions.
At the network layer, considerable research and development has been
recently focused on the use of small cellular base stations. However,
those cells have only been considered as mere extensions to cellular
networks, allowing the enlargement of service coverage. The use of
these small cells, mostly deployed by consumers, has not yet been
fully explored. There are many services and protocols in the network
that could benefit on the scattering of this kind of cell deployment.
This project will exploit the opportunities that small cells will bring to
improvement on the network architecture. The aim is to a achieve a
much richer small cell, that will provide better support for several
services and protocols that could take advantage on a distributed
architecture
and/or
context
ware
and
localized
information.
Femtocells can have many benefits for both operators and users. From
an operational or deployment perspective however their integration
into the network is quite hard. From the user perspective the
deployment of those cells has to be transparent, therefore support for
zero-configuration networking is a requirement. This project will
exploit network access characteristics of being self-organized inherent
to the SON specification of LTE-A. The project will include specific
activities to study mobility management, considering its implication
network efficiency. The aim will be to support simultaneous data flows
from LTE-A and other access systems (WLAN, WiMAX), provide policies
for guiding and configuring the UE IP flow routing via different access
systems, enable the dynamic movement of IP flows between access
systems (offloading) and support handovers when the UE handles
multiple
flows.
Cross-layer
Media

standardization efforts have been done on several working groups in
IEEE, IETF and 3GPP. However the implementation of those media
independent handovers has not yet fully considered the use of
Femtocells in the network. For instance, in IEEE 802.21 access
selection is out o scope of the standard, which is simply an integration
enabler for multi-access radio access technologies. Femtocells will be
used

multi-Access, multi-homing is another novel aspect to consider in
femtocells. In particular this project will go beyond “3G complemented
by 3rd party access” scenarios, paving the ways for true multi-access,
multi-homing where each flow can influence the access selection
process.
The project will take advantage of Femtocells in multiple ways. The
project will exploit the fine-grained context awareness made possible
by the use of Femtocells in order to support the provision of content
rich services by increasing the user’s Quality of Experience (QoE).

OPPORTUNISTIC-CR
Opportunistic Aggregation of Spectrum and Cognitive Radios:
Consequences on Public Policies
Funding
FCT/PTDC
Descript.
Networks
of
the
future
are
tending
towards
a
diverse
wireless
networking world, where scenarios define that the end-user will be able
to attain any service, at any time on effectively any network that is
optimized for the application at hand resulting in “flexibility and choice”
to enhance the quality of life of the individual, in a context of seamless
interoperability and cognitive radio between network operators and
access technologies, complemented by a business exploitation strategy
that adapts to future economic infrastructures.
Advanced algorithms for multi-band access/selection will be explored to
optimize the offered capacity whilst maintaining the user service
experience acceptable. Also secondary users may have temporary
opportunistic access to free spectrum ''holes'' or a set of users may
simultaneously utilize, optionally, spectrum resources in lower/upper
frequency bands, improving the quality of experience. The consequences
of this new perspective for spectrum management in public policies will
be addressed as well as the impact of having secondary spectrum
markets.
From the technical point of view, modeling, simulation and experimental
approaches will be followed, e.g., by using emulators with a hardware
component
within
academic
and/or
industrial
partnerships
to
be
developed.
Spectrum usage optimization is one of the goals of our Project, fig. in
Annex (Orlando.png). The opportunistic utilization of spectrum holes by
secondary users will be investigated by implementing novel MAC designs
regarding sensing cooperation and opportunistic transmission that will
use cross layer and cross system information. Another objective is to
attend to the increasing demand of higher data rates. Spectrum
aggregation (SA) is a technique that attempts to increase spectrum
utilization and it is therefore a coming solution to support the 100 MB/S
over a wireless connection. After World Radiocommunication Conference
2007 (WRC07) the new bands to be considered for International Mobile
Telecommunications - Advanced (IMT-Advanced) were 450-470, 698862, 790-862, 2300-2400, 3400-4200 and 4400-4990 MHz. In order to
support the increasing demand of high data rates bandwidths of 100MHz
have to be considered. These bandwidths can only be achieved by going
to high frequencies. The drawback of going into high frequencies is the
high propagation losses and the Doppler Effect on high velocities.
Multi-hop and Infrastructural users will be managed by a Multiband
Common
Radio
Resource
Management
(MB-CRRM)
entity.
This
management will be direct in the Infrastructural case scheduling
user/group of users in a given frequency and indirect in the multi-hop
case (secondary users) by demanding or leaving a control channels open
for secondary user coordination and taxation. The management of
secondary users will be performed by making hopping frequency
directives so that a dynamic coordinated secondary use of the spectrum
can be made.
The MB-CRRM has the ability to optimize frequency scheduling for
infrastructural users, and also frequency scheduling for secondary usage.
While each system maintains control over his RRM entity, including the
distributed secondary system, the MB-CRRM entity will make them more
dynamic radio wise.
A wide and local MB-CRRM optimization could be differentiated. By wide
MB-CRRM it is meant frequency planning for all the systems being
considered in a given area considering several base stations (BSs).
Local MB-CRRM optimization addresses the integration of the distributed
secondary system as well as optimization of neighboring infrastructural
cells. Infrastructural wise, overall packet scheduler that will account for
BSs
power,
available
capacity,
frequency
will
be
developed.
Secondary system will follow frequency hopping directives provided by
the local MB-CRRM that will be an output of the local MB-CRRM.
Parameters to be optimized involve: transmission power, frequency
carrier, carrier bandwidth, control channel frequency and power, service
reliability and quality.
The
economic
vision
targets
a
converged
network
and
service
infrastructure for communication, computing and media applications that
will create new market opportunities for 3^rd party service providers.
The drive for ubiquitous, cost-effective communication in unison with
new service provisioning opportunities provided the impetus for the
OPPORTUNISTIC-CR proposal. It intends to design, implement and
demonstrate “cooperative networking and optimization strategies” for
next generation networks that will provide a significant step towards
network convergence in a truly heterogeneous environment. Multi bandcommon radio resource management strategies are considered, assisted
by a prediction tool/algorithm that provides the future position and
traffic demand of a mobile node for maximizing network resources utility
and QoS delivery. By assuming a secondary usage of the spectrum, it is
ensured the spectrum utility maximization. These visions will be
complemented by a business feasibility study, and will include innovative
graphical cellular planning tools.
Simulations (Opnet and/or ns-2 and system tools build in C++) as well
as laboratory prototypes will be used for validation purposes. The team
members have both WiMAX and WiFi hardware available in their
institutions,
where
the
proposed

Title
Virtual Traffic Lights
Funding
FCT/PTDC
Descript.
Urban transportation is one of the grand challenges of our times. Car
journeys are by far the main player in this transportation, comprising
72% of all passenger kilometers in the European Union (EU) [1]. Traffic
congestion on the road is thus a common reality of the major EU cities,
and has been estimated to cost as much as 1% of the GDP. In its
present form, the use of Traffic Lights (TL) to control and regulate this
road traffic has proven to be very costly and inadequate in terms of
scalability. Leveraging the new vehicle-to-vehicle (V2V) communication
capability of modern cars we propose to design and validate an
alternative scheme of urban traffic control that envisions TL as in-vehicle
virtual signs, enabling ubiquity of signalized intersections, and defining
the synchronization of light phases, cycle durations and green splits
based on distributed and self-organization techniques that govern a
vehicular ad hoc network (VANET).
The non-scalability of TL, and in particular the non-scalability of an
adaptive and intelligent citywide system of TL (a recent survey reports
that 70-90% of the deployed TL are non-adaptive [2]) is a key aspect
that we shall address through the alternative approach proposed in this
project. Even New York City only has 10,800 of its 45,000 intersections
managed by TL [3]. In other cities this percentage is typically smaller. In
addition to traffic flow improvement, TL have also a significant impact on
road safety, as studies report a 33% decrease in vehicle crashes at
intersections
that
have
been
equipped
with
traffic
signals
[4].
Our approach in this project will take advantage of the mandatory
adoption by the automotive industry of the Wireless Access for Vehicular
Environments
(WAVE)
protocol,
and
the
ability
of
vehicles
to
communicate with each other, thus creating a distributed and highly
reliable system of in-vehicle virtual traffic lights (VTL). Our preliminary
simulations of this self-organizing traffic paradigm show a potential to
increase the average flow rates substantially (up to 60%, compared with
a city-level physical TL system [5]), in addition to rendering traffic
control and management more ubiquitous and cost-effective. Our basic
idea is relatively simple: use the core characteristics of VANET, namely
periodic beaconing, location tables and appropriate transport and MAC
protocols to perceive crossing conflicts and elect a leading vehicle that
works as a temporary virtual infrastructure, stopping under a virtual red
light at the entrance of the intersection and broadcasting virtual traffic
light messages that are listened by the vehicles approaching the
intersection. Local optimization of cycle duration, phase layout and green
splits are computed based on the number of vehicles in each approach.
City-level optimization of traffic flow can resort to the synchronization of
leaders in adjacent intersections or even to a traffic information system
that also leverages on VANET communication. Devices on each vehicle
interpret the VTL messages and display the respective color to the
driver. We envision the computing, communication and display device to
be possible to retrofit on the existing car park, and the project will
produce such devices. By providing unequivocal evidence of the
envisioned
approach
on
the
mitigation
of
traffic
congestion,
its
economical and environmental impact, and increased road safety, the
project intends to pave the way for the adoption of EU legislation
towards
the
equipping
of
all
vehicles
with
VTL.
Our project is a natural follow-up of the DRIVE-IN (Distributed Routing
and Infotainment through Vehicular Inter-Networking) project, funded
by the Portuguese Science and Technology Foundation and involving an
international partnership with Carnegie Mellon University in the US.
DRIVE-IN has been designing VANET communication protocols and
developing high-scale traffic models and simulators that will support the
design and validation of the in-vehicle VTL system. DRIVE-IN has also
deployed a prototype VANET in the city of Porto, resorting to 450 taxis

Scope and Objectives
In the following, the achievements in the Optical Communications area
are grouped, under three sub-areas:
• Optical Components and Subsystems
• Optical Communication Systems
• Optical Networking
4.2.3.3
Expertise and research topics for research
Optical components and sub-systems
The work carried out in this sub-area concentrated on the modeling,
performance evaluation, optimization and implementation of key
components and subsystems for all-optical networks.
Quantum Communications
In addition to Bell’s original inequality, John Clauser, Michael Horne,
Abner Shimony, and Richard Holt (CHSH) developed a special form of
Bell’s inequality which gives classical limits to the expected correlation
between two particles. We presented a theoretical demonstration of
the maximum value for violation of CHSH inequality, for the pure
entangled quantum state. Using the spontaneous four-wave mixing
process, we generated polarization-entangled photon pairs in a highly
nonlinear fiber (HNLF) loop, for experimental verification. Using a nonentangled quantum state, it was shown theoretically that the violation
of CHSH inequality is only a property of entangled states. We have also
shown the theoretical solution of violation of the CHSH inequality for a
general Greenberger–Horne–Zeilinger state and for an arbitrary state
of two particles.
The photon statistics of a single-photon source based on the stimulated
four-wave mixing (FWM) process was studied. We studied also the
impact of the FWM process on a co-propagating coherent quantum
signal in a wavelength-division multiplexed (WDM) lightwave system.
The statistics of the quantum signal changes from Poissonian to
thermal when a low power is used, and remains Poissonian for a higher
power. A multi-thermal regime is also observed when moderate power
is used.
Our studies included the investigation of the effects of waveguide loss
and nonlinearities on the generation of polarization entangled photon
pairs through spontaneous four-wave mixing (FWM). Those effects
were quantified through the analysis of the coincidence-to-accidental
ratio (CAR), and through the Clauser, Horne, Shimony, and Holt
(CHSH)
inequality.
Our
findings
showed
that
a
high
value
of
coincidence counting rate does not necessarily lead to a strong
violation of the CHSH inequality.
A method for compensation of polarization in optical fibers, which can
be used in real-time quantum communication systems, was developed.
This method does not demand the use classical signals or any other
additional devices. Also, it can be used for any transmission rate or
encoding protocol. A continuous test was performed in a 5 km optical
fiber.
We
also
presented
a
model
for
the
QBER,
which
was
experimentally validated.
Numerical Modeling and Simulation
A numerical model was developed for continuous wave (CW) supercontinuum generation in a highly nonlinear fiber (HNLF) pumped in the
normal dispersion regime on. We have obtained experimentally
spectral broadening by pumping a non-microstructured HNLF with a
CW signal from a Raman fiber laser. The experiment was simulated
using a generalized Schrödinger equation containing the actual Raman
response of the fiber as calculated from the experimental Raman gain.
Some of our efforts focused on a low complexity computational model
for the gain profile and amplified spontaneous emission noise for
broadband counter-pumped Raman fiber amplifiers. The proposed
model is based on two adjustment parameters used to account for the
interactions between the pumps. The obtained results show a good
agreement
between
experimental
measurements
and
detailed
numerical simulations, for different combinations of pump wavelengths
and pump powers, with a processing time several times lower than the
time taken by a detailed numerical model.
The Transfer Matrix Method (TMM) was optimized for the stationary
and dynamical analysis of different non-conventional DFB laser diodes.
Some aspects referring the dynamical aspects still need a more
detailed analysis. Recent work has been developed towards the
matching of TMM to the finite element method (FEM), in order to
optimize the optical coupling between waveguides, taking into account
the geometrical and material parameters concerning the optical
devices.
The frequency response of dual depletion PIN photodiodes continued to
be investigated. The devices were assumed to have the drift region
next to the N contact and with the light incident on the N side. Both
the transit time and the capacitive effects were included in the model
which also took into account the effects related to non-uniform
illumination and variable electric field in the absorption region. The
FEM was used to compute the frequency response and the results
compared well with those from a semi-analytical model.
Koch's model for chirp assessment in semiconductor single mode lasers
was extended for operation at high laser bias currents which is
required by high bit rates transmission. Detailed numerical simulations
showed that Koch’s model fail in predicting accurately the chirp at high
laser bias currents, and the proposed model provides a better
description of chirp.
Components Development and Production
Improvements were obtained in the production setup for optical fiber
micro-wires (OFMs). Micro-wires with a diameter as short as 600 nm
can now be produced. Techniques were developed for deposition of
diamond and grapheme in optical fibers for advanced sensors and
optical processing. Work was carried out on the development of thermo
actuated
integrated
modulators)
for
optics
passive
devices
optical
(Y-branch
networks,
splitter
based
on
and
MZ
sol-gel
technologies. Design techniques were established for production of
devices based on periodically-poled Lithium Niobate (PPLN).
A platform for production of optical filters in plastic optical (POF) fibers
was developed and implemented. This will enable the realization of
advanced communications systems and sensors based in plastic optical
fibers. We also implemented state of the art FBG fabrication system for
POF fibers. In the area of transmission of high power optical signals in
fiber systems, our studies included the constraints resulting from the
fiber heating and strategies for the mitigation of the fiber fuse effect.
All Optical Signal Processing
In relation to all-optical polarization control, a device based on Raman
scattering was developed. It was shown that the device can operate
over a wavelength range of 60 nm. Nevertheless, the efficiency of the
pulling process is higher close to the Raman gain peak, where the
degree of polarization is roughly constant for a wavelength range of 15
nm.
Optical fiber micro-wires (OFMs) are promising nonlinear optical
waveguides that support several spatial modes. The multimodal
generalized nonlinear Schrödinger equation (MM-GNLSE) was deduced
for this waveguides taking into account the linear and nonlinear modal
coupling. A detailed theoretical description of four-wave mixing (FWM)
considering the modal coupling was developed. Both, the intra-mode
and the inter-mode phase-matching conditions were calculated for an
optical micro-wire in a strong guiding regime. Finally, the FWM
dynamics was studied and the amplitude evolution of the pump beams,
the signal and the idler were analyzed.
We also developed techniques for all-optical processing using acoustic
waves in optical fibers. By applying tunable acoustic waves in fibers it
is possible to adjust the properties of optical filters based on fiber
Bragg gratings. The applications include adjustable gain equalization
for
EDFAs,
adjustable
notch
filters
and
tunable
dispersion
compensators.
Experiments and measurements were performed aiming at implement
and demonstrate an all-optical static random access memory (RAM)
cell
with
read/write
functionality,
using
optical
flip-flops
and
semiconductor optical amplifiers (SOAs).
The developed work includes a flexible OTDM to WDM converter based
on a wavelength selective switch and the experimental validation of
optical phase regenerators based on periodically-poled Lithium Niobate
(PPLN) devices.
In addition to the techniques described in more detail in this report, an
range of other techniques were developed for all-optical routing,
tunable dispersion compensation, optical filtering, pulse shaping, clock
recovery, optical code division multiplexing and regeneration.
All-optical transforms for image processing is a new research line,
which aims at diversifying from the traditional transmission efforts at
IT, in order to open new paths for future research efforts where image
processing and energy will be critical.
Sensors
New sensors based on FBG and POF technologies were developed for
monitoring strain, humidity, temperature, viscosity and chemical
sensors
for
integrated
monitoring
of
surface
water
quality.
Experimental assessment was carried out for refractive index optical
fiber sensors for monitoring of Madeira wine vinification process,
wastewater treatment process and soil erosion processes in recently
burnt forests. Other optical fiber sensors were studied for: monitoring
of the polymerization reaction of dental materials, hemodynamic
assessment, refractive index, anion recognition. Our studies included
also nanodiamond coated Bragg gratings for sensing applications and
graphene coated optical fiber devices for sensing and communications
applications.
4.2.3.4
Optical communications systems
The work carried out in this sub-area of optical communication systems
focused on optical packet switching, techniques for performance
evaluation of optical communication systems and networks, optical and
electronic signal processing techniques for transmission systems
implementation / optimization, techniques for performance evaluation
of optical communication systems and networks, radio over fiber
systems and use of few mode fibers.
Optical Packet Switching
A complete optical router with included label recognition, all-optical flip
flop, all optical picosecond switches and wavelength converters was
demonstrated at our labs in the beginning of 2012. A new all-optical
packet monitoring technique was developed which allows monitoring of
the optical signal-to-noise ratio (OSNR).
Signal Processing for High-Bit Rate Optical Communications
Employing
keying
100G
polarization-multiplexed
(PM-QPSK)
signals,
we
quaternary
experimentally
phase-shift
demonstrate
the
performance of the Volterra series nonlinear equalizer (VSNE) to
mitigate
intra-channel
nonlinearities
(studied
in
2011).
The
performance of the dual-polarization VSNE was assessed in both
single-channel
and
in
wavelength-division
multiplexing
(WDM)
scenarios. Considering near-optimum optical/electrical filtering, we
have shown that the dual-polarization VSNE is able to outperform the
back-propagation split-step Fourier (SSF) method in the nonlinear
regime. Being intrinsically single-step, the VSNE also tends to require
less computational power.
Techniques based on Volterra model were investigated for transmission
impairments
mitigation
in
dispersion-managed
and
–unmanaged
coherent communication systems. It was shown that the effectiveness
of these techniques decreases with the symbol rate. In dispersionunmanaged coherent QPSK systems, these techniques show reduced
interest
in
28
Gbaud
systems
but
considerable
performance
improvement in 10 Gbaud systems. In dispersion-managed coherent
QPSK systems, these techniques provide performance improvement
comparable to digital back propagation with one step per span, for the
dispersion maps of interest.
A Stokes space based polarization demultiplexing technique for
polarization-switched QPSK signals was also developed. This Stokes
space based technique shows an improvement of more than on order
of magnitude in terms of convergence ratio when compared with the
modified constant modulus algorithm (CMA).
A Stokes space based technique for digital polarization-dependent
losses (PDL) monitoring and compensation was proposed. The channel
PDL monitoring is carried out with a resolution of 0.15 dB by
computing the mean point of the signal samples represented in the
three-dimensional
Stokes
space.
The
presented
compensation
technique is based on rotations and translations of the signal samples
in the Stokes space, and provides a PDL compensation of up to 2.5 dB.
Error vector magnitude results show a gain of about 3 dB (assuming a
PDL value equal to 1.5 dB) compared with a Stokes space based
polarization demultiplexing technique without PDL compensation.
Some novel schemes to construct large sets of perfect sequences for
communication systems with CDMA, derived from an Inverse Discrete
Fourier Transform (IDFT), were proposed. Furthermore, new methods
have been developed to create optimum sets of new bipolar codes
derived from bi-dimensional orthogonal perfect sequences. Different
CDMA communication systems have been simulated with the new
perfect sequence families. All simulations have shown how the new
perfect sequences and almost perfect sequences should be useful in
communication systems. For an OCDMA system, the coder/decoder
selected was the SSFBG (Super Structured Fiber Bragg Grating).
Techniques
for
Performance
Evaluation
of
Optical
Communication Systems and Networks
A method for rigorous performance assessment of direct-detection
(DD) baseband OFDM communication systems, based on the moment
generating function, was developed for arbitrary optical and electrical
filters, and OFDM signal characteristics. The method was numerically
validated using Monte Carlo simulation. Work on the generalization of
the method to consider the electrical RF transmission and the impact of
I/Q demodulator imperfections on the performance of DD-OFDM optical
communication systems has been initiated.
A study of the behavior of eigenfunctions and eigenvectors in DD DPSK
optical systems was performed in order to improve the method of
performance evaluation of those systems. The impact of homodyne
crosstalk with multiple modulation formats on the performance of DD
DPSK optical communication systems and networks was characterized.
The rigorous formulation of performance evaluation of DD DPSK optical
systems was generalized to take into account homodyne crosstalk from
optical network elements. The impact of in-band crosstalk in optical
DQPSK systems and OOK crosstalk signals was evaluated using Monte
Carlo simulation and an analytical model for the single interferer
scenario.
Radio Over Fiber Systems
Initially, an important part of the research on Radio Over Fiber
Systems focused on the development of models for simulation of the
transmission over fiber of modulated signals used in advanced fixed
and mobile communication systems, such as baseband gigabit Ethernet
OFDM signals, long term evolution (LTE) signals, and orthogonal
frequency division multiplexing (OFDM) ultra-wideband (UWB), in
accordance with the current standards. These tools were subsequently
used to study the decomposition of the chirp parameter into two novel
parameters in accordance with two different chirp sources. We studied
also the impact of the modulation chirp of a dual-electrode MachZehnder modulator on OFDM signals transmitted over wavelength
division multiplexing (WDM) long-reach passive optical networks
(PON). In 2012, our studies included simulation and experimental
evaluation of RF propagation over fiber; the RF signals included TDT
and satellite (video) and OFDM-UWB radio signals.
Techniques for linearization of electro-optical converters for multiformat OFDM-based PONs in the optical and electrical domain were
investigated. In the optical domain, a dual parallel Mach-Zehnder
modulator (DPMZM) used for electro-optic conversion of multi-band
OFDM UWB radio signals in intensity modulated-direct detection optical
communication systems was optimized theoretically and through
numerical simulation. In the electrical domain, the linearization
performance of a digital pre-distorter using a MZM and a directly
modulated laser was evaluated numerically and experimentally.
Optical Transmission Systems based on Mode Group Diversity
The main progresses made in this topic were: design of phase masks
for minimization o modal crosstalk, for fibers with two linearly
polarized modes; development of a method for semi-analytic solution
of the system of coupled linear differential equations that describe
modal crosstalk in few mode fibers; design of few mode fibers with
reduced differential mode delay; study of the impact of fiber splices on
the long reach high bit rate transmission over few mode fibers.
Digital Signal Processing for Optical Communication Systems
An area of increasing importance for implementation of modern
systems is digital signal processing techniques, which were used for
channel impairment mitigation and laser phase noise reduction. Also, a
transceiver for LTE based systems was implemented on an FPGA. The
receiver includes synchronization and equalization.
4.2.3.5
Optical networking
The work on optical networking has continued, with special emphasis
on next generation transport networks, next generation access
networks and cable networks.
Optical Transport Networks
We developed a statistical model for link lengths in optical transport
networks. From the analysis of statistical properties of real networks, it
was found that General Extreme Value (GEV) distribution provides an
accurate model for link length statistics of optical transport networks.
It was shown that the optimized GEV distribution estimates the link
statistics
of
optical
transport
networks
with
good
accuracy
(Kolmogorov-Smirnov statistic less than 0.18).
Our research efforts included also the impact of node architecture on
power consumption and footprint requirements of optical transport
networks. Fixed and flexible transport nodes were compared as
regards power
consumption
and
the number
of
required
slots
(footprint). Results of our studies show that to optimize the total power
consumption and footprint of the network, the architecture of each
node has to be selected according with the amount and pattern of the
add/drop and regenerated traffic, and the number of pairs of fibers
convergent on the node. An optimization method based on simple rules for node
type selection was proposed.
Our studies included the network evolution from current WDM systems
towards elastic optical networks, based on flexgrid transmission and
switching
technologies,
able
to
carry
a
wide
range
of
signal
bandwidths, varying in real time, direction and magnitude, some of
which will be extremely large possibly exceeding 1Tb/s. Optimization
procedures for planning flexible-grid optical networks supporting traffic
based on super channels were developed.
Other areas of our research efforts were the problem of all-optical
network resources allocation in the scope of impairment aware based
routing for the next generation optical networks; and multilayer
interworking and optimization, in order to obtain a more effective
combination of optical and electronic switching /routing.
Multilayer optical networks were also investigated. In particular, the
design and modeling of MPLS/OTN networks using both ILP (Integer
Linear Programming) formulations and heuristics were performed.
Optical Access Networks
In the area of access networks the efforts have been put into the
development
of
models
of
reflective
devices
as
RSOAs.
The
demonstration and modeling of ultra-high density flexible access
networks was also pursued. Raman amplification was characterized
considering its application to Passive Optical Networks and the use of
optical powering for remote nodes.
Evolution strategies for the next-generation passive optical networks
were studied. In particular, Next Generation Optical Access (NGOA)
Networks were investigated taking into account different scenarios and
applications,
including
wire
line
and
wireless
convergence
for
distributed antenna systems and radio astronomy applications. GPON
standards and evolution towards NGPON (topologies and modulation
formats) were studied. Convergence scenarios considering GPON,
XGPON, NGPON (TWDM, UDWDM) and video overlay were studied and
their coexistence experimentally validated. Work was also carried out
in the area of support for time synchronization in Ethernet. The
activities in 2012 dealt with timing and synchronization in the DPoE
Network architecture (DPoEv2 primarily) and P802.3bn EPoC project.
Part of our activities in 2012 focused on standardization of physical and
logical layers of Ethernet PON (EPON) through technical (submission of
technical contributions) and organizational (editorship, involvement in
the development of standard draft) participation in the IEEE 802.3
Working Group (with the focus on physical layers of EPON) and IEEE
1904.1 Working Group (with the focus on the logical layer and service
layer interoperability of EPON systems). More than 500 technical
contributions were submitted to 1904.1 WG (restricted access, due to
WG membership policy), including technical comments, presentations,
and editorial contributions. We participated also in the FSAN and IEEE
standardization committees, which was important for the identification
of the specific problems of access networks.
Considerable effort was allocated to the participation in the European
project FIVER. In FIVER project, four OFDM-based signals (custom
signal bearing GbE data, WiMAX, LTE and UWB - bands 2 and 3 signals) are used to provide quintuple-play services to end users along
wavelength division multiplexing (WDM) long-reach passive optical
networks (LR-PONs). The simultaneous transmission of those four
OFDM-based signals along wavelength division multiplexing (WDM) LRPONs was demonstrated experimentally. Particularly, the transmission
performance of those four signals was evaluated for different LR-PONs
reaches, considering single-wavelength and WDM transmission. A
compensation algorithm of impairments of LR-PONs was proposed,
demonstrated experimentally and its performance improvement was
assessed experimentally in the downlink using a conventional directly
modulated laser (DML). The assessment was accomplished for different
LR-PON distances and in the absence and presence of optical
dispersion compensation.
From the joint work between IT and Corning, the distribution of the
different FIVER services along a LR-PON comprising conventional
standard single-mode fiber (SSMF) and ultra-bendable Clear Curve
Corning fibers was demonstrated. The link from optical line termination
(OLT) to remote node (RN) was bridged by 75 km of SSMF. The optical
network units (ONUs) were then connected to the RN via the ultrabendable Clear Curve Corning fiber. In addition, 20 bends with radius
of 1 cm were introduced in order to show the effectiveness of the
bendable fibers.
The performance degradation induced by linear crosstalk on the multiformat OFDM-based signals due to the finite selectivity of the
demultiplexer used in the RN was assessed experimentally for different
channel spacing values. Additionally, the nonlinear crosstalk induced
by the fiber nonlinearity on the bundle of OFDM signals was also
assessed experimentally.
The bidirectional FIVER network was implemented off-line in the
laboratory. The OFDM-GbE, LTE, WiMAX and two UWB channels were
considered for the downstream (DS) transmission. In the upstream
(US), only the OFDM-GbE, LTE and WiMAX signals were transmitted.
The setup was implemented using external modulation (using MZM) for
the DS and DMLs for the US path.
The impact of the power distribution between UWB, LTE, WiMAX and
OFDM-GbE signals on the performance of the different OFDM-based
signals was assessed considering the LR-PON of FIVER project.
Particularly, the optimum power distribution between the multi-format
OFDM-based signals was identified through numerical simulation.
The distribution of digital video broadcasting (DVB) terrestrial (T)
format to the final users using the FIVER LR-PON was proposed. In this
way, a fully integrated wired-wireless hybrid infrastructure capable of
handling with the different technologies required to satisfy the users’
demand was obtained. The impact of transmitting the DVB-T format
into the OFDM bundle of signals was assessed through numerical
simulation and discussed. Additionally, the impact of inserting two RFpilots close to the DVB-T signals for channel sounding on the
performance of the bundle of OFDM signals proposed to provide the
quintuple-play service to the end users was assessed and discussed for
LR-PONs reaching 75 km and 125 km.
A numerical simulator used to evaluate the degradation of the OFDMsignals bundle induced by the fiber nonlinearity of the FIVER LR-PON
was also developed. The degradation due to the fiber nonlinearity was
evaluated through simulation of the generalized nonlinear Schrödinger
equation using the split step Fourier method with step of 100 m. The
analysis was performed for single wavelength transmission and
considering WDM transmission.
Evolution of Cable Networks (DOCSIS)
WE Participated in DOCSIS Provisioning of EPON (DPoE) project
development, taking advantage of EPON as a transport layer for
DOCSIS provisioning signaling. Phase 2 of this project is currently
under way, and aims at adding support for more advanced MEF
services (Ethernet Virtual Private Line - E-VPL, Ethernet Tree - E-TREE,
or Ethernet LAN - E-LAN), coexistence between 1G-EPON and 10GEPON at the physical layer as well as support for multicast services
with advanced customer authentication. In 2012, more than 300
technical contributions were delivered to various DPoE specifications,
with the primary focus on physical layer, security (encryption and
authentication), MAC layer and OAM design.

Title
Steering of light in nonlinear waveguides with resonant interactions
Funding
FCT/PTDC
Descript.
This project aims to study the steering of light in different nonlinear
systems with internal resonances. Nowadays such systems attract a
great deal of attention because modern technologies allow to produce
devices where internal resonant interactions between light and
material excitations result in huge optical nonlinearities, providing a
rich plethora of nonlinear effects at relatively low power. These huge
nonlinearities and the flexibility of physical parameters make such
devices very attractive for different practical applications, including
guidance of light, information processing, and generation of new
frequencies. In addition, such systems constitute laboratories to study
fundamental nonlinear phenomena. This project addresses several
kinds of physical systems and devices. We consider hollow-core
photonic crystal fibers filled with gases of multi-level atoms whose
resonant frequencies match the frequency band guided through the
fiber. In these systems, the matter-light interactions are not only
strong
because
of
their
resonant
nature,
but
are
also
easily
manageable through the control of the coupling field on the other
hand. Systematic investigation of the nonlinear dynamics will be
undertook, starting from the study of the propagation of the
continuous radiation in simple geometries, but also looking into the
dynamics of short pulses, to the formation of optical solitons, and to
their mutual interactions in more sophisticated geometries, like
coupled waveguides, networks of waveguides, couplers, etc.. The
formation and stability of solitons, representing coupled states of light
and matter, i.e. a kind of polaritons, is expected to be strongly
affected by the waveguide characteristics and by the material
dispersion of the media. Hence, it will be explored how the
propagation of short pulses can be steered by the slowly varying
quasi-continuous waves and by additional short pulses. Effective
models describing linear and nonlinear effects by taking into account
the quantum mechanical description of the interactions will be
developed, giving special attention to the impact in the propagation of
solitons of dissipation, particularly dissipation due to spontaneous
emission from the excited states of the multilevel atoms, material
losses and imperfect guidance of the light. When dissipation is weak
enough we can speak about quasi-solitons propagating at long
distances, whereas in the quantum regime, when dissipation is strong
enough, we can expect manifestations of the Zeno effect. We also
investigate how the dissipation affects not only the maximum
propagation distance of the solitons, but also their shapes and
stability. Technologically it is possible to manufacture a multi-core
fiber filled with active gases. For these fibers, it is important to study
the interaction between the pulses propagating in the neighbouring
cores and find out the conditions of effective energy transference
between modes. We plan to address this problem analytically and by
extensive numerical simulations. We also investigate semiconductor
microstructured systems, which are another important kind of the
waveguiding systems produced on semiconductor chips. The main
advantages of these systems are their small sizes and the possibility
to pump them by external continuous sources of the light. Cavity
solitons can survive in these systems until the pump is switched off.
The bright and dark solitons can be controlled by the pump and by
weak control signals. This type of systems can be used as optical
memories and for information processing, as well as, on the
generation of new frequencies. We also consider systems consisting of
a semiconductor thin film which serve as planar waveguide for the
light and can be pumped by a coherent light due of imperfect
guidance. The resonant nonlinearity arises from stimulating excitons
with resonant frequency coinciding with the cut-off frequency of the
planar waveguide. Consequently, it is possible to excite quasiparticles
with very low group velocities, commonly known as polaritons and
resulting
from
the
resonant
coupling
of
light
and
mater excitations, which provides very strong nonlinearities. This
allows
the
optical
formation
of
structures
resting
at
or
low
slow
moving
pumping
localized
powers.
Meta-material waveguiding systems consisting of weakly nonlinear
dielectric films with build in metallic nanoparticles are also considered.
The nanoparticles provide polariton resonances playing a role similar
to the exciton resonances. These systems will be modelled rigorously,
starting from basic quantum-mechanical theory. We will investigate
the dynamics of the solitons in detail using analytical and numerical
methods.
The
possibility
of
controlling
the
solitons
by
weak
perturbations of the pump, as well as, the resonant mutual interaction
between cavity solitons and between the solitons and quasi-linear
waves will also be investigated.

In-band crosstalk in optical communications systems with differential
direct detection
Funding
IT
Descript.
This project is within the optical communication networks area. In
particular, in the area that studies the physical constraints in optical
networks.
One of the most severe limitations in the network physical layer is
crosstalk. This phenomenon has its origin, primarily, in the imperfect
isolation
of
optical
components,
such
as
optical
switches,
multiplexers, and demultiplexers, that are key components in the
design of an optical node. The type of crosstalk that causes the higher
degradation to the system performance is the in-band crosstalk, in
which the interfering (crosstalk) signals and the selected signal,
despite coming from distinct optical sources, have the same nominal
wavelength.
The main objectives of this project are:
* Develop a formalism to evaluate the impact of in-band crosstalk in
optical DQPSK systems.
* Evaluate the impact of in-band crosstalk in a DPSK and DQPSK
systems when the signal propagates through an optical network. Each
optical node is formed by an optical switching architecture, optical
amplifiers, optical filters, and possibly wavelength converters.
* Implement Monte Carlo (MC) simulation to study the impact of ASE
noise and in-band crosstalk on the performance of DPSK and DQPSK
systems and confirm the analytical results.
* Implement the multicanonical Monte Carlo (MMC) method to
simulate the tails of the probability density function of the decision
variable and to obtain lower values of the bit error rate (BER) than in
the MC standard procedure.
* Evaluate by simulation the impact of in-band crosstalk in optical
networks with DPSK and DQPSK signals, for a rigorous model of the
optical node and validate the analytical tool developed for this case.

- To develop cost-effective solutions for extraction of phase and
amplitude information from the optical field, using advanced signal

techniques
to
reduce
the
hardware
requirements
associated with coherent detection;
- To develop and implement efficient and simplified digital postcompensation algorithms using the phase and amplitude information
of the optical field in order to enable real-time mitigation of linear and
nonlinear propagation impairments, with low computational power;
Future high-speed optical communication systems will inevitably rely
on new enabling technologies such as advanced modulation formats,
coherent detection and receiver-side digital signal processing. In order
to apply these technologies to commercial optical communication
systems there must be a strong I&D effort to develop efficient and
low-cost solutions. This is currently a fast growing investigation topic,
which
need
to
be
faced
in
many
different
fronts,
such
as:
- Study of propagation and receiver performance of different advanced
modulation formats;
- Analysis of network architectures and optical devices in order to
reduce the impact of propagation impairments;
- Development of efficient and cost-effective solutions for coherent
detection both in metro and access networks;
- Development of digital adaptive post-compensation algorithms for
the
mitigation
of
linear
and
nonlinear
impairments.
Within the framework of this project we will focus mainly on the
development of cost-effective coherent receivers, using advanced
digital signal processing techniques in order to reduce the hardware
requirements. Besides, taking advantage of the amplitude and phase
information provided by coherent detection, we are also going to
develop
digital
post-compensation
algorithms,
in
order
to
simultaneously enable higher bit-rates, narrower inter-channel spacing
and longer propagation distances without sacrificing the received
signal quality.

We will fabricate and characterize highly nonlinear fibers obtained by
tapering standard optical fibers. Highly nonlinear fibers will be used to
produce a super-continuum and to implement two all-optical signal

modulated signals based on self-phase modulation (SPM) and ii) an
all-optical signal processing regenerator for nonlinear phase noise
reduction based on four-wave mixing (FWM) suitable to be used in
phase modulated signals. An accurate numerical modelling and the
design optimization of both tapered fibers (TFs) and microstrutured
fibers (MFs) will be realized, in the perspective of their use to generate
a wide and flat super-continnum, as well as some nonlinearity-based
optical signal processing functions, namely the wavelength conversion,
all-optical switching and 2R regeneration.

Bragg Gratings in Plastic Optical Fibre for communications and

Funding
FCT/PTDC
Descript.
The possibility of the fibre to the home (FTTH) for simultaneous
transmission of different services such as internet, telephone, digital
television is, in fact, actual. Polymer optical fibres (POF) are being
pointed as a lower-cost and viable alternative to glass fibre in shortdistance applications. The use of this type of fibre has several
advantages such as simpler and less expensive components, ease to
hande and connect and has greater flexibility and resilience to
bending, shock, and vibration. Moreover, FBG is passive and versatile
device that has been used in the development of components and
techniques for optical communication systems with high capacity.
With this strategy we intend to reduce cost and in the same time
don’t
compromise
the
spectral
efficiency.
The global aim of this proposal is to develop new techniques and new
innovative devices based on FBG written in mPOF for optical
communications and sensing technologies.

4.3.3.2
The general medium term research direction in IT-Networks and
Multimedia will aim at several goals:
• A global network integrating multiple technologies and services,
providing end-to-end quality of service (QoS), ubiquitous access,
and security. The common denominator of such heterogeneous
global network will almost surely be the Internet Protocol (IP).
• New ways of storing/communicating, retrieving/accessing,
processing, and presenting large volumes of multimedia data text, still images, video, and audio.
The area of Networks and Multimedia includes 74 researchers with a
PhD degree, and more than 130 PhD students and other collaborators.
The research in this scientific area is organized in groups, with their
main future research goals and topics of expertise are listed below.
4.3.3.3
Expertise and topics for future research
4.3.3.4
Information Theory
• Investigation of fundamental communications limits of wired and
wireless communications systems;
Investigation of the fundamental security limits of communications
systems;
• Study of the interactions between information theory and estimation
theory, and their
optimization
of
applications in the analysis, design and
communications
systems
and
in
physical-layer
security;
• Investigation of the realization of common signal processing tasks
(such as detection, estimation, classification, regression) within the
paradigm
of
compressed
sensing/sampling,
mainly
targeting
applications to imaging systems.
Interactive Miltimedia
• Set the infrastructure and logistics to run three research labs on:
computer
graphics,
computer
vision,
and
human-computer
interaction;
• Set the foundation of 3d synthetic characters and how they behave in
virtual and real environments.
• Study and deploy a character animation pipeline to create look-a-like
avatars;
• Study and deploy a markerless facial motion capture system that
uses low-cost equipment, such as web-cams;
• Create an animation system that automatically animates 3d facial
models based on the markerless facial motion capture data;
• Realize a game prototype for the recognition of facial emotions using
our facial sketching technique, and reproduce facial expressions from
a specific person, wearing a head-mounted display, into a synthetic
3d avatar.
Multimedia Signal Processing
• Application of multi-fractal theory for medical image and video
analysis;
• Automatic discrimination of breast tumors in ultrasonic images:
quantification and classification of breast tissue density and study of
its variance in the neighborhood of breast tumor lesions.
• Design and development of a 3d holographic video codec, taking into
account the perceptual characteristics introduced by the channel, the
target display, and the human visual system.
• Development of robust acoustic modelling methods, by automatic
segmentation of speakers, linguistic and non-linguistic events and
speech utterances in broadcast programs.
• Study of voice pathologies and dysarthria, using signal analysis and
acoustic models for speakers with voice disorders.

3D VIVANT
Title
Live Immerse Video-Audio Interactive Multimedia
Funding
EU, FP7
Descript.
The aim of the project 3D VIVANT is to capture events automatically in
3D and deliver them for realistic, interactive and immersive play back to
home users-viewers. This will require the project to create, develop and
integrate a comprehensive range of components from the generic
technology of 3D imaging. Real and virtual 3D content will be
homogeneously combined/mixed producing a novel form of rich and
interactive content, defined as “3D Holoscopic content”. 3D Holoscopic
imaging is a technique for creating full colour 3D optical models that
exist in space independently of the viewer. The images exhibit
continuous parallax throughout the viewing zone. The continuous nature
of the images produced with this method eliminates the effect of
'cardboarding' (flattening of objects into discrete depth planes) and
flipping (a visible effect created by moving between image fields)
present in multiview stereoscopic systems. Unlike multiview stereoscopy,
information about a point is contained in many different parts of the
image plane. In this respect 3D Holoscopic imaging is akin to
holography. However 3D Holoscopic imaging is more advantageous,
since it can operate under incoherent illumination, which is in contrast
with holography, and hence it allows more conventional live capture and
display procedures to be adopted. Furthermore, in viewing the 3D optical
model accommodation and convergence work in unison (i.e. the viewer’s
eyes focus and converge to the same point) to prevent eye-strain from
occurring.
The 3D VIVANT project will investigate the possibility of using different
technologies for capture and display of 3D content. For the capture, 3D
VIVANT will take full advantage of 3D Holoscopic imaging technology,
where a single camera is required. Hence in this project a world first
single aperture ultra-high definition 3D Holoscopic imaging camera will
be constructed which will permit live capture of 3D content. For the
display, the project will take advantage of Holography to provide
immersive, ultra high resolution presentation of 3D content. To increase
the immersive experience, the generation and playback of 3D spatial
sound is also investigated. The developed system will be tested using
two user cases, namely, broadcasting and online hyperlinking. For this
purpose various 3D Holoscopic video processing algorithms, such as 3D
codecs and 3D object segmentation, as well as search and retrieval
techniques will be developed.

Title
3D video adaptation based on perceptual metrics
Funding
National Science Foundation - QREN
Descript.
The research work in this project is focused on 3D video stream
adaptation methods capable of maximizing 3D perceptual quality under
different sets of known constraints. The joint interdependencies between
rate,
3D
perceptual
distortion
and
decoding
complexity
will
be
investigated using subjective evaluation and validation procedures.
Adaptation of 3D video streams is mainly targeted at rate, format and
decoding complexity adaptation, taking into account that 3D video
includes more parameters suitable for adaptation which provide an
increased level of flexibility (e.g., the 3D signal is coded into two
streams which might undergo through different channel errors and
constraints, variable depth distortion in the spatial and temporal
domains producing similar perceptual quality, asymmetric distortion in
stereoscopic
video,
effect
of
error
concealment
methods
in
3D
perception, etc). The project research is also concerned in devising
power-aware
adaptation
functions
such
that
decoding
power
consumption is reduced at the expense of minimum quality cost. This is
an open topic for research in 3D video since decoding is far more
complex than monoscopic video and the need for low complexity
decoding
is
higher
because
of
limited
battery
life
and
lower
computational resources in portable decoders.

Title
3D Video Quality Monitor
Funding
IT
Descript.
The project is focussed on research and development of 3D video
perceptual quality monitoring in error prone networks, such as the near
future 3DTV services over IP or DVB networks. The challenge is to
establish a set of (Quality of Experience) QoE metrics and their
relationship with objective measurements that affect the overall QoE.
These metrics are computed from a combination of transport network
layer information, quality features of 3D video signal and coding
parameters embedded in compressed streams. The project seeks to
investigate No-Reference (NR) methods such that blind 3D quality
assessment can be carried out at any point of the delivery chain
including the receiving terminal. Such an approach is rather more
challenging than Full-Reference (FR) or even Reduced-Reference (RR)
methods, where either the original signal or partial information about it
is available.

The goal of this project is twofold:
1. to get a deeper insight into the manifestations of Mild Cognitive
Impairment (MCI) and Alzheimer 's disease (AD) both in space and time
dimensions
2. to produce more accurate diagnosis tools using PET images of the
brain.
In order to achieve these goals, we propose to develop automatic
classification tools for PET brain images to:
1. differentiate between Alzheimer's disease (AD), Mild Cognitive
Impairment
(MCI),
and
normal
control
subjects
(NC).
2. distinguish between MCI patients who convert to AD (MCI-C) from
those
who

3. identify individual patterns of disease evolution, by assessing
morphological changes along the time, based on follow up scans for each
patient.

Secure Multimodal Biometric Recognition System using Distributed
Source Coding
Funding
FCT/PTDC
Descript.
Biometric recognition systems target the automatic recognition of a
person’s
identity
based
on
physical,
physiological
or
behavioural
characteristics (something a person is or produces). In particular,
verification systems perform one to one authentication, comparing the
captured biometric data with that person’s own biometric template (a
mathematical representation of the biometric features extracted during
the
enrolment
phase)
previously
stored
in
the
system.
One of the major vulnerabilities associated to biometric recognition
systems is that once a biometric template becomes compromised, it
cannot be reissued, updated or destroyed. An attacker could then gain
access
to
all
the
accounts/services/applications
using
that
same
biometric trait. The main goal of the project is to create a secure
multimodal biometric verification system, supporting the generation of
different templates from the same biometric data, as well as cancellable
templates. Furthermore, the privacy of the original biometric data needs
to be guaranteed, not allowing its recovery from the stored data.
State-of-the-art methods will be extended by considering a biometric
verification system based on distributed source coding principles and
cryptographic hash functions, to enhance security with respect to
traditional biometric systems. The additional consideration of multimodal
biometrics
helps

ComFormCrypt
ComFormCrypt - Computational
Semantics of Formal
Methods in
Cryptography
Funding
FCT-PTDC
Descript.
This project addresses the problem of correct symbolic abstractions of
cryptographic primitives for the purpose of symbolic, automated proving
of security properties of protocols.
Computer security has been of major interest in the past two decades.
This field provides both interesting research problems and important
applications to everyone's life such as e-commerce and e-government,
hence the need for designing better and safer security protocols. Proving
security of protocols however is a difficult task that sometimes cannot be
performed by hand, therefore several tools have been designed to deal
with such a complex problem [B01,BMV05,P98]. But the need for such
(automated) tools is not only due to the complexity of the protocols. If
we consider the simple protocol proposed by Needham and Schroeder in
1978 [NS78], it was not until 1996 that Lowe discovered his famous
attack on the protocol using the CSP-model checker FDR [L96] and
suggested a fix. The attack used a flaw in the protocol design, the
encryption itself was assumed to be perfectly secure. With this ''perfect''
cryptography assumption the protocol is simple enough to be easily
analyzed by standard model-checkers and theorem provers. The fix was
shown to be safe as long as encryption was perfect. But what happens
when the cryptographic primitives are not perfect, which is the case in
real life where we can always guess a key with small probability? After
some positive results regarding cryptographic soundness of such
abstractions, Warinschi [W03] showed that the same attack discovered
by Lowe against the NS protocol, could be performed against the
corrected version if a somewhat weak but standard encryption scheme is
used, the El-Gamal encryption scheme. This result turned the attention
of the research community for the need of soundness results for formal
cryptography, ie, the importance to characterize when protocols proved
correct using perfect cryptography are correct when implemented with
computational
cryptography.
Computational
soundness
of
formal
cryptography is an active research area and members of this team have
been involved in several of its fronts
[ABS05,ABHS05,ABHS09,AF06,AFGZN08,BHO07,BHO09,BMS06]
Symbolic models provide abstractions for the study of cryptography that
are amenable for automatic verification of complex protocols but assume
''perfect cryptography'' [DY93]. Messages, keys, encryptions, attacks, all
appear as formal objects described with symbolic operations, axioms,
derivation rules; cryptographic operations are modeled as functions on a
space of symbolic expressions and security properties are also treated
symbolically. This method ignores the probabilistic nature of encryptions.
It provides a powerful way to describe how an adversary may interfere,
corrupt, deceive participants of a protocol, and grab this way information
not
addressed
to
him.
This
method
is
much
easier
to
handle
mathematically than the computational, the proofs can be automated
but, as the probabilistic nature is ignored, security within this framework
does not necessarily mean security in the real world. Real probabilistic
attacks that are outside the framework of this model may still happen
[W03]
On the other hand in the computational model cryptographic operations
act on strings of bit and their security properties are defined in terms of
probability
and
computational
complexity
[GM84].
Computational
security proofs make use of techniques of these theories; proofs have to
be done by hand (ie cannot be automated) and are different for each
protocol. Good protocols are those in which attackers cannot do
something bad too often and efficiently enough. This is a very detailed
description, closer to reality as it involves the notion of efficient
computation, hence complexity and probabilities. However, even for
mildly complex protocols this approach simply becomes too difficult and
impossible to handle.
The unification of these two models is absolutely necessary for symbolic
security proofs to be trustable. So far in the literature there are
fragmented attempts done by different research groups, but as their
treatment lack sound mathematical basis, the results themselves and
how they are related are questionable
AR02,ABHS09,AF06,BPW03,C01,CC08,DDMST05,MW04]
We expect this research project to deliver new insights to the
relationship between the symbolic and computational models, clarify the
applicability and limitations of existing approaches to this problem, and
provide sound mathematical foundations that can be used in the future
as a common framework and technique for sound symbolic abstraction
of new cryptographic primitives.
The ultimate goal of this research is to develop/adapt fully automated
tools for symbolic models that, via our soundness results, entail strong
cryptographic
guarantees
to
the
computational
model,
hence
substituting the tedious complexity-theoretic proofs of computational
cryptography by automated ones

Integrating Biometrics and Forensics for the Digital Age
Funding
COST-ESF
Descript.
Forensics is the application of a broad spectrum of sciences to answer
questions of interest to a legal system. This may be in relation to a crime
or a civil action” [Wikipedia]. Since many such questions boil down to
identifying, or verifying the identity, of people allegedly involved in some
action, a clear relationship exists between forensics and biometrics.
Biometrics developed a number of techniques which can clearly facilitate
the identification of people involved in criminal actions or civil incidents.
Thus, although the two communities have traditionally often operated in
relative
isolation,
there
are
many
scenarios
where
the
synergic
cooperation of multimodal biometrics and forensics can be successfully
applied. To address such multifaceted areas it is important to develop an
interdisciplinary network with complementary competences, to foster the
birth of a new community which can develop novel technological
solutions to crucial issues and new challenges in forensic science.
The Action will promote new partnerships, will provide education and
training, will contribute to develop new standards and best practices, will
produce awareness of the potential benefits of advanced technologies for
evidence analysis in forensic cases and will stimulate improved mutual
understanding of collaborative working models linking the academic and
industrial sectors.

This project is meant to support a three-way collaboration between ITLisbon, IT-Coimbra, and Aalto University in Helsinki, Finland. The three
research groups involved have two things in common: they all work in
blind source separation (BSS) in situations where the typical approach
through Independent Component Analysis (ICA) is not appropriate; and
they
all
apply
these
techniques
to
biological
signals.
Our proposal is to pool together the e orts of the three research groups.
They have recently worked in two main domains: separation of phaselocked subspaces; and separation of cardiac sounds. Although these two
domains are very di erent, they share several aspects: 1) they are both
inverse problems; 2) the observation model is linear; 3) the sources are
assumed to be statistically dependent. The team will develop novel
algorihms to tackle these two separation problems, based mainly on two
approaches: matrix factorization and Bayesian inference.

The potential of the Internet of Things is leading to a paradigm shift with
an ambitious long-term vision, in which battery-operated sensing nodes
are empowered with sight and are capable of complex visual analysis
tasks. Unfortunately, this is out of reach with the current technology.
GreenEyes will develop a comprehensive set of new methodologies,
algorithms and protocols, to empower wireless sensor networks with
vision capabilities comparable to those achievable by power-eager smart
camera systems. The key tenet is that most visual analysis tasks can be
carried out based on a succinct representation of the image, which
entails both global and local features, while it disregards the underlying
pixel-level representation. Still, under severe energy constraints it is
imperative to optimize the computation, the coding and the transmission
of the features. On the computation and coding side, GreenEyes will
tackle the problem by reversing the conventional compress-then-analyze
paradigm. That is, image features are collected by sensing nodes,
processed, and delivered to final destination(s) in order to enable higher
level visual analysis tasks by means of either centralized or distributed
detectors and classifiers, somewhat mimicking the processing of visual
stimuli in the early visual system. The transmission of visual features is
subject to tight application-dependent requirements (bandwidth/delay
guarantees), and may be affected by network conditions. Therefore, on
the communication side, GreenEyes will pursue the design of networking
tools for wireless multimedia sensor networks for energy efficient
distributed control, information delivery and in-network processing
optimized for the visual analysis task.

Funding

Descript.
The main goal is to pursue interdisciplinary research involving muscle
physiology, biomechanics and neuromuscular control. The actual focus is
to conduct research for the evaluation of biomechanical load on the
musculoskeletal system. Our underlying hypothesis is that the increasing
of the amount of exercise can positively influence biological tissue
morphology
and
functional
mechanical
properties.
Nevertheless,
excessive loading, both in intensity as well as frequency and volume, can
be associated to acute and chronic musculoskeletal impairments. We aim
to study the effect of specific mechanical loads in the musculoskeletal
system, with special emphasis in the muscle-tendon complex, and the
cartilage.
The
study
will
be
centered
on
architectural/structural,
functional and neuromuscular chronic and acute changes associated to
the mechanical load supported while the body is undergoing exercise
routines,
of

loading.
To accomplish the study of the biological tissue chronic and acute
adaptations to cyclic mechanical loading two complementary approaches
will be used: (1) in vivo imaging methodologies (magnetic resonance
imaging - MRI - and ultrasonography - US); (2) biomechanics modeling.
We are concerned with the changes in muscle and tendon stiffness,
cartilage thickness and collagen arrangement. The neuromuscular control
systems are sensitive to neural fatigue, and this can be measured
through EMG. These changes will be assessed and introduced into the
models throughout the redefinition of the activation process. Structural
and functional analysis of cartilage and muscle-tendon complex before
and after mechanical load will be available from MRI and SE. The
resulting information will be correlated and those changes will be related
with the estimated joint loading (using biomechanical modeling). All this

MUlti-view distributed coding for VIsual Sensor networks
Funding
FCT/PTDC
Descript.
Distributed video coding (DVC) is a compression paradigm based on two
key Information Theory results from the 70s: the Slepian-Wolf and the
Wyner-Ziv theorems. Contrary to the available predictive video codecs,
DVC codecs exploit the source statistics at the decoder providing
functional benefits such as: 1) flexible distribution of the computational
complexity between encoder and decoder; 2) in-built robustness to
channel losses; 3) exploitation of Inter-view data correlation at the
decoder.
These functional benefits are very important for visual sensor networks,
a network of wireless low-power video camera nodes, used for a wide
range of applications such as surveillance, monitoring of remote areas or
tele-presence systems. Visual sensor networks are characterized by: 1)
Inter-view correlation between camera nodes with overlapped views; 2)
up-link communication between many encoders (one at each camera
node) to a few decoders; 3) independent compression of each view,
since collaboration between cameras is difficult to implement or rather
inefficient.
Due to these characteristics, it is not efficient (or possible) to compress
each captured view at a central node with the typical predictive
approach, e.g. using the recent multi-view video coding H.264/MVC
(Multi-view Video Coding) standard, since it implies to exploit spatial,
temporal and Inter-view correlations at a rather high complexity
encoder.

location, forcing communication between cameras. This project will
advance state-of-the-art by developing competitive multi-view DVC
solutions
for
visual
sensor
networks,
notably
by
proposing:
1. Side information (SI) creation and correlation noised modeling: To
fully exploit the potential of the multi-view distributed video coding
paradigm, high quality side information (an estimation of the source
created at the decoder) must be created by (jointly) exploiting temporal
and Inter-view correlations. In this case, solutions that combine
temporal and Inter-view SI estimators by using preliminary decoded data
as helper information will be proposed. In addition, correlation noise
models capturing the statistical correlation between the side information
(available
at
the
decoder)
and
the
source
(available
at
the
encoder) will also be proposed along with the estimation of the relevant
parameters.
2. Hybrid predictive-distributed video coding: The combination of
predictive coding techniques, to exploit the temporal correlation, with
distributed coding techniques, to exploit the Inter-view correlation, may
be a successful “cocktail” to obtain improved rate-distortion (RD)
performance. This approach was never exploited before (as much as the
authors know) and will require to reinvent popular coding techniques at
both encoder and decoder. In this case, it is also expected to obtain
error resilience improvements, which is quite important in this type of
error-prone networks (typically wireless).

Title
Next Generation Network Operations and Management
Funding
FCT/CMU
Descript.
Effective network management has been widely recognized as a grand
challenge. Enterprise networks spend an increasing amount of their IT
budgets (up to 70% in 2008) in order to only maintain their current
operating environments, rather than to add new, value-adding services
and equipment. A $1000 server that demands annual maintenance cost
of $2000 illustrates a simple example of the management problem. This
excessive cost of network management is mainly due to the large scale
of networks, the heterogeneity of different technologies, and their subtle
interactions. The goal of NeTS is to develop a novel network operation
and management framework that departs from conventional approaches
through a cross-disciplinary research collaboration based on hierarchical
network
abstraction
modeling,
structure
learning
of
probabilistic
graphical models for machine learning, and wavelet and kernel-based
signal processing technologies. In multiple phases, NeTS will be
progressively deployed in the Portugal Telecom (PT)’s operation and
management of high definition IP/TV network to illustrate the impact of
our proposed research. High Definition IP/TV network is one of the
highest growth services for PT and is regarded as a key strategic area in
PT. The grand challenge of this complex network is to deliver, without
failures,
a
high
quality
service
efficiently
–
this
requires
novel
management/operations systems to detect anomalies, identify their
root-causes, and predict future network behavior in real time. Existing
network management systems for IP/TV are generally focused on
monitoring and on simple correlation of events analysis; using these
management systems still incurs in excessive costs and delays. NeTS will
be deployed online in part of PT’s IP/TV network in order to assess its
performance and expected network operations and management cost
reduction. Network operators will play a key role in assessment and finetuning of our systems. Our approach to this research problem is
significantly different from conventional approaches that focus on
monitoring and correlation analysis. We bring together insights from
network abstraction and statistical and heuristic machine learning
methods and closely tie them to build an intelligent network abstraction
model. Network insights show that the network configuration dictates
the behavior of the network control plane and the network control plane
dictates the behavior of the data plane. We bring configuration, control
and data plane abstraction models together with probabilistic graphical
models to derive an intelligent and predictable network abstraction
model of an enterprise network. Further novelty of our approach consists
of performing automatic learning of the graph structure using concepts
from Bayesian model selection, information theory, and optimization;
this will be done step-by-step using first static network configuration
elements, then by summarization and filtering of dynamic control plane
information, and finally of data plane information. Once a graphical
model is obtained for the network, we will perform inference on the
graph to identify anomalies and their root-causes and to predict future
network behavior. Finally, we will explore the concept of forcing function
to impose restrictions on the network configuration that simplify the
graphical
model
and the inference process. This project
heavily
leverages on previous network abstraction modeling work with PT in last
3 years. The direct impact of this research will be on the network
operations and management of PT’s IP/TV service. Although at this point
it is not possible to say what the real impact will be, we anticipate a
reduction of at least 30% on network operations and management costs.
This is supported by the anticipation that support teams will be directed
to a single extremely likely root cause of a failure rather than to multiple
possible failure points, that root-causes will be detected in the time-span
of seconds rather than days, that service may be brought up in minutes
s rather than days, and that network behavior and failures may be
anticipated, thus reducing down time several orders of magnitude. We
expect other enterprise network-supported services may also benefit
from NeTS because the network modeling and management functions
researched
in
this
project
are
generic
to
enterprise
networks.
To achieve NeTS’ goals, we formed an interdisciplinary team that
includes experts in Networking (Dr. Sobrinho, IT/Lisboa, Dr. Kim,

as Optimization (Dr. Xavier, ISR/Lisboa). Furthermore, we obtained a
strong collaboration commitment from Portugal Telecom with their
operational experiences and manpower that will be explored during all
phases of the research project (see attached letter of support from PT).
We plan to integrate several PhD students who are already enrolled in
(e.g. Tiago Carvalho and Tiago Quelhas) and in the process of applying
to the CMU-Portugal program. It is also important to note that we have
created various PhD-level courses within the CMU-Portugal program in

responsibility for advanced courses within the CMU-Portugal Master’s

several

pressure,

etc) and possess signi cant embedded processing and low-range wireless

(WSN)
where

the
use

is
crucial
to
assess
the
state
of
a
physical
system, the ultimate engineering goal is to control such system to
perform certain desired tasks. We refer to systems that close the loop
around
wireless
sensor
networks
as
cyber-physical
systems
(CPS). Cyber-physical systems are physical and engineered systems the

and

To realize the immense potential bene ts of CPS in real-life applications,
a plethora of novel problems lying at the intersection of statistical signal
processing, control, communication theory, and distributed optimization,
must be addressed. Indeed, it is clear that to achieve desired
networkwide
detection,
estimation
or
control
objectives,
system
designers should deal eciently with simultaneous challenges, typically
tackled in separate engineering disciplines. The challenges include
securing energy-ecient operation as the nodes are usually batteryoperated and constrained to small power budgets, developing distributed

interconnecting the sensing nodes, dealing with the random nitebandwidth wireless medium, etc. The need for this interdisciplinary
e ort is mirrored in the creation of this project's research team which
gathers signi cant expertise in a wide range of complementary topics in
the disciplines of control, signal processing, optimization, information
theory, along with the private technology company ISA (Intelligent
Sensing Anyhwere) which holds a vast experience in the deployment of
sensing networks for telemetry, environmental monitoring and energy
eciency.
The main goal of this project is to address certain key research issues in
the eld of wireless sensor networks and map the research results into
implementations on prototype testbeds, thereby showcasing real-life
applications with social and economic impact. More precisely, the
expected outcomes of this project are:
1. Fast algorithms for sensor selection While energy-eciency is of a
lesser
concern
in
wireless
LANs,
it
is
of
critical
importance
in
large-scale wireless sensor networks (WSN), as the in-situ unattended
sensors are typically powered by nonrechargeable batteries. Thus,
aggressive restraints on sensor usage must be observed to ensure a
prolonged WSN lifetime. When the WSN is used for event discrimination
(e.g., intruder/no intruder, re/no re, etc) this translates into nding which
minimal subset of the deployed sensing nodes is sucient to activate for a
given query, whilst securing a prescribed detection performance. It is
clear
that
nding
the
optimal
subset
of
sensors
represents
a formidable optimization challenge. Indeed, forming all possible
combinations of few sensors and checking the respective performance is
computationally
intractable
even
for
moderate
network
sizes.
Additionally, a WSN is typically immersed in a noisy environment subject
to various degradation factors such as wireless fading and interference
phenomena. These induce communications constraints between the
sensors themselves or between the sensors and a fusion point
responsible for the decision. It is thus important to explicitly account for
the impact of this adverse phenomena in the design of reliable sensor
selection algorithms. In this project, we will develop fast (noncombinatorial) optimization algorithms for several sensor selection
application scenarios which strike a desirable tradeo among detection
performance, computational complexity and robustness with respect to
the fading wireless medium.
2. Secure WSN communication schemes Security is an issue of
paramount
importance
in
current
communications
systems
and
networks.
The wide deployment of wireless sensor networks, together with the
broadcast nature of the wireless medium, calls for advanced secure
mechanisms to protect potentially sensible information against possible
eavesdroppers.
Traditionally, security is viewed as an independent feature with little or
no relation to the remaining data communication tasks and, therefore,
state-of-the-art cryptographic algorithms are insensitive to the physical
nature of the wireless medium. However, there has been more
recently a renewed interest on information-theoretic security - widely
accepted as the strictest notion of security - which calls for the use of
physical-layer techniques exploiting the inherent randomness of the
communications medium to guarantee both reliable communication
between two legitimate parties as well as secure communication in the
presence of an eavesdropper. This paradigm is particularly interesting
for wireless sensor networks since it may not be possible to secure
information
using
state-of-the-art
complex
cryptographic
protocols
due to energy budget considerations. In this project, we will study the
fundamental
security
mechanisms
pertaining
to
the
sensor
network communications medium by exploiting tools from information
theory. In addition to revealing the secrecy limits of wireless sensor
networks,
we
will
also
construct
speci
c
transmission
schemes
appropriate to convey information between sensors and a fusion point
in a reliable and secure manner, taking into account the energy and
bandwidth restrictions of sensor networks.
3. Secure Control of Cyber-Physical Systems Modern cyber-physical
systems raise signi cant engineering challenges because of their scale,
their need to bridge the physical, information and communication
technology domains and their need to operate eciently, securely and
reliably. Today's methods and tools for control systems engineering are
unable to systematically cope with such requirements. Security, in
particular, must enter the design process and cannot be considered an
afterthought. Today's designs are mainly driven by performance/cost
considerations, resulting in brittle systems susceptible to attacks starting
from
both
the
physical
and
cyber
side.
The
problem
arises
because CPS tend to be open systems, accessible both physically and
through the communication network. The increasing use of the Internet
will allow attackers to execute their attacks remotely. Next generation
systems
will
be
particularly
susceptible
to
security
threats
if this concern is not addressed at design time. CPS, di erently from
traditional IT systems, not only have to be able to detect malicious
attacks but they need to guarantee continuity of operations under
attack,
perhaps
with
decreased
functionality,
through
graceful
degradation rather abrupt. They also need to be able to recon gure to
eradicate attacks and restore full functionality. We propose to introduce
a
new
approach
to
control
systems
design,
by
formally
de ning security attacks on control systems and by developing tools to
analyze the e ect of security attacks, to design attack resilient control
systems and develop quantitative metrics to assess the natural tradeo
between security and performance.
4. Testbed and Implementation We propose the employment of an
experimental
platform
to
validate
the
outcomes
of
the
research. ISA will assist in de ning the set of applications that better
align with both their business and with the current market trends. We
will adopt the Sensor Andrew platform available at Carnegie Mellon at
the
rst
stage,
with
the
plan
to
enhance
the
platform
and
deploy a smaller scale testbed at IST in Portugal at a later stage. Sensor
Andrew is a project aimed a building a large scale wireless sensoractuator network infrastructure on the CMU campus. The testbed
comprises the basic sensor and actuator hardware, the software
that runs on this hardware allowing access to the sensor and actuator
hardware, and nally the network protocols and services required to
support communications and routing within large-scale sensor networks.
We plan to build an event noti cation system that will allow us
to perform sensor selection, event detection and real time control using
the Sensor Andrew platform. At the core of the system is the use of an
XMMP server that allows timely retrieval of selected sensor data and
delivery of control commands. This infrastructure will allow us to
validate the proposed methodologies and algorithms in a real setting, to
assess its robustness to uncertainties and resilience to security attacks.

Fusion of Palmprint and Iris Recognition in Uncontrolled Environments
Funding
IT
Descript.
The main objective of this project is to design a biometric identification
system to be used in uncontrolled data acquisition scenarios. In order to
do this, and thus enjoy all the advantages of this type of systems
mentioned above, there are four main challenges that have to be solved.
These challenges can be summarized as:
- Acquisition of data with enough discriminating information - This is a
fundamental phase in devising any biometric application. The data
acquisition setup (operating wavelength, type of illuminant, levels of
luminance, number and position of illumination sources) and the protocol
demanded to subjects play a crucial role in the quality of the acquired
data and determine the success of the biometric recognition task. Thus,
a convenient data acquisition framework should be devised in the
earliest stages of the project.
-
Accurate
biometric
data
segmentation
-
As
mentioned
above,
traditional biometric applications, such as computer access and border
control, require the user to submit a biometric in a highly controlled
manner. In this kind of constrained biometric capture, users take
deliberate actions to cooperate with the biometric systems, such as
facing forward and standing still. This makes it easier for the system to
extract the biometric information from the raw image/video data, by
performing a simple segmentation. However, when the acquisition
scenario is relatively uncontrolled, the acquisition system will have to be
able to perform a much more sophisticated segmentation to extract the
desired biometric information from the raw image/video and guarantee
that
it
is
not
confused
with
noise,
which
can
be
quite
high.
- Correction of pose and illumination variations - After being able to
extract the biometric data (i.e., determine its exact location) from the
raw image/video data, the system has to deal with the problem of pose
and illumination variations due to unconstrained biometric capture. After
all, when the capture is done in an uncontrolled fashion, the biometric
data can have different sizes, different orientations, different degrees of
deformation and be subjected to different types of illumination, all of
which have to accounted for in order to be able to perform a successful
user recognition. This process of dealing with the captured data
variability can be seen as form of normalization.
- Robust user identification - After the biometric data has been
normalized, robust recognition algorithms have to be developed for
performing
the
identification
itself.
To
improve
the
identification
performance, more than one biometric trait can be considered, in which

and feedback is severely degraded, and 2) improve the probability of
correct reception of the information after the handover, when the exact
knowledge of the status of the terminals is unknown. These two steps
shall be instrumental in achieving a seamless handover. The choice of the
number of coded packets to be sent before and after the handover needs
to take into account several issues, such as the mobility pattern of the
mobile terminal, signal variation in both the previous and the new access
networks, handover time and the expected performance degradation
while handover is taking place. Moreover, the decision of handover with
network coding needs also to be addressed, since it is required to
evaluate the cost of handover (in terms of signaling and performance
decrease) and the additional cost of introducing coding, both in the extra
amount
of
information
delivered
and
its
delay
in
real-time
communications. In this approach, we will target Wi-Fi networks and the
handover of smart phones between different Wi-Fi access points. The
evaluation of our approach will be performed through simulation in the
network simulator and on a seamless mobility platform previously
developed between IT and PTInovação.

Title
Gestão de Mobilidade Centrada no Utilizador Final
Funding
FCT/PTDC
Descript.
The work to be developed in this project relates to the topic of global
mobility
management
in
spontaneous
wireless
environments,
i.e.,
environments that self-adjust to any network topology change. Global
mobility management is addressed from a network perspective, and the
purpose is to ensure a transparent access to Internet services (e.g Triple
Play) for the end-user, who will be able to access his/her subscribed
services independently from access attachment point, location, and based
upon his/her own requirements (“Quality of Experience”, QoE). In
addition, global mobility management is to be analyzed from a decentralized perspective, given that environments to be considered will
incorporate wireless local-loops that are based upon end-user willingness
to cooperate. Main aspects to focus upon are:
1. Handover management optimization
a. Consider QoE as well as available (aggregated) spectrum to provide the
user with the best possible connection seamlessly at any time and
independent
of
location,
having
in
mind
user
expectations.
b. Analyze and validate adequate cost functions and metrics to estimate
QoE levels on-the-fly.
2. User-centric mobility management
a. Investigate and validate algorithms for a self-organized selection of
anchor-points, aiming to insure system robustness to highly frequent
changes.
b.
Devise
a
global
mobility
management
mechanism
taking
into
consideration the aspects analyzed in relation to handover optimization
and incorporating mobility models that support adequate anchor point
selection.

Title
VERE: Virtual Embodiment and Re-Embodiment
Funding
EU, FP7
Descript.
This project aims at dissolving the boundary between the human body
and surrogate representations in immersive virtual reality and physical
reality. Dissolving the boundary means that people have the illusion that
their surrogate representation is their own body, and act and have
thoughts that correspond to this. The work in VERE may be thought of as
applied presence research and applied cognitive neuroscience, and it
would also significantly add to scientific knowledge in these areas .
Imagine that you could transfer your self to an artificial body – a virtual
body as represented in virtual reality or a physical robotic body. Recent
advances in cognitive neuroscience show that internalising a body beyond
ourselves
(external,
remote,
alien)
is
possible,
that
our
body
representation is highly malleable and may be altered by appropriate
changes to the normal stimulus contingencies that we are used to in
every day life.
The purpose of this research is to make such body transference possible
with two different modes (virtual and physical). On top of this technical
achievement, that would be underpinned through ongoing neuroscience
research on body representation, would be a number of practical
applications that will be constructed and investigated during the project.

Title
Voice Coach for Reduced Stress
Funding
FCT/PTDC
Descript.
VOCE shall develop methods and algorithms that enable the online
classification of stress from live speech with the goal of providing
feedback cues to the speaker in real-time to improve his communication
skills. The work will focus on detecting and classifying stress in speech by
leveraging advanced signal processing and machine learning techniques,
complemented with psychological analysis of different aspects of stress
perception.
Specifically,
the
tasks
shall
produce
the
following
deliverables:
1) a large database of spontaneous speech samples multiply tagged for
being used in the development of automatic stress recognition methods;
2) speech feature extraction algorithms that are capable of real-time
performance, as well as the tagging of the samples in the database.; 3) a
reduced set of features relevant for stress classification, a classification
algorithm that can classify stress levels in real-time, a benchmark
evaluation of the various machine learning approaches to automatic stress
classification, using similar evaluation methodology and sample data set;
4) an application that integrates the results of the previous tasks and
evaluate its accuracy and response times, both in laboratory settings with
elicited emotions and in real-life trials.

4.4.3.2
Applied Electromagnetics – Lx
The Group of Applied Electromagnetics conducts research activities in
the broad domain of the Electromagnetic Field Theory and its
applications to electric, magnetic, and electronic devices. In 2012 the
following interrelated subjects have been addressed:
• Transmission-line structures
• Electric and magnetic field problems
• Optical waveguides
• Computational methods for electromagnetic field evaluation
4.4.3.3
Group
Transmission-line structures
research
on
transmission-line
structures
is
multifaceted,
encompassing theory and applications, and aiming at a variety of
targets.
The topic of magnetic transmission lines has been addressed. Signal
transmission in magnetic transmission lines (MGTL) is assured by means
of parallel magnetic-flux carrying magnetic wires as opposed to the
familiar situation of electric transmission lines (ELTL) where parallel
current-carrying electric conductors are utilized. A novel quasi-TEM
theory for uniform homogeneous two-wire magnetic transmission lines
has been developed based on Maxwell equations. It has been concluded
that while ELTLs behave as low-pass filters, MGTLs behave as high-pass
filters.
The problem of the numerical evaluation of the series-impedance
parameters (resistance and inductance) of uniform overhead power
lines, taking into account transversal variations of conductivity and
permeability of line conductors and soil, was analyzed and solved by
resorting to a developed method that employs elemental current strips
instead of current filaments.
The effect of power-line sagged conductors on the evaluation of the
differential voltage in nearby railway circuits was analyzed using
traditional matrix methods for multi-conductor lines; results have been
validated through direct electromagnetic field computation.
Magnetic fields produced by underground power cables can endanger
human safety. The important problem of magnetic field mitigation using
shielded cables was solved numerically via a FEM/BEM technique.
4.4.3.4
Electric and magnetic field problems
Group research on electric and magnetic field problems is multifaceted,
encompassing theory and applications, and aiming at a variety of targets.
Electric and magnetic fields generated by a set of periodically distributed
filamentary conductors in a circular arrangement have been evaluated;
results obtained involve the computation of a continuous product of
distances. In close connection with the computation of such a continuous
product, the general algebraic problem of the factorization of a sum or
difference of two powers has been addressed. An application to bundled
conductors has been examined.
Problems related to contactless energy transfer (CET) are usually dealt
with in the framework of transformer theory, employing equivalent
electric circuits as a tool for their analysis. A physics approach, based on
Maxwell equations, has been developed to tackle CET systems. Electric
and magnetic fields are utilized to evaluate the Poynting vector; the
concepts of magnetic voltage and magnetic flux are utilized to define the
instantaneous power guided within the magnetic transmitter. An analysis
of the electromagnetic field guided and emitted by the transmitter has
been developed; electromagnetic energy leaving the transmitter being
evaluated using short-dipole antenna theory.
An inductive system comprising four sensing coils wound around an aircore, traversed by an off-centered tilted current-carrying primary wire,
has been analyzed. A magnetic vector potential based approach has been
developed aimed at the determination of closed-form expressions for the
induced voltages appearing at the open terminals of the four sensing
coils, all of them depending on the 3D position of the primary wire. The
inverse problem of the determination of the primary wire position based
on the coils induced voltages has also been formulated, but only exactly
solved for the case of an off-centered wire parallel to the core axis.
An analysis of skin-effect like phenomena in radially inhomogeneous
tubular geometries that fit in the category of Euler-Cauchy structures
(ECS) has been carried out. The per unit length complex magnetic
reluctance of tubular ferrites has been evaluated, considering that their
complex permeability strongly depends on the frequency. The motivation
for this research is linked up with the theory of magnetic transmission
lines whose behavior critically depends on the complex magnetic
reluctance of its wires. The analysis has mainly focused on high frequency
regimes up into the GHz range.
4.4.3.5
Optical Waveguides
Group research on optical waveguides encompassed two topics:
Electromagnetic propagation in bent and ring slab waveguides and lasers.
Analysis of waveguide dispersion in strongly biaxial anisotropic optical
fibers.
4.4.3.6
Computational methods for electromagnetic field
evaluation
• The development of computational methods and software tools for
electromagnetic field calculation is key for most of the above reported
research activities of the Group.
Research Outputs in 2012:
• 8 papers in international refereed scientific journals.
• 1 paper in an international refereed conference with published
proceedings.
• 2 MSc supervisions (completed).
• Upgrade of a national patent to the international domain
4.4.3.7
The research of the Group of Applied Mathematics in Telecommunications
has been focused on Optimization and Numerical Linear Algebra. The
members of this group have been working on establishing new theoretical
results concerning existence and uniqueness and convergence analyses of
algorithms for the solution of some important problems in Linear Algebra
and Optimization.
Furthermore they have been devoted to the design,
implementation and testing of algorithms for the solution o these
problems. Collaboration with engineers on the solution of some models of
engineering, namely in telecommunications, has be enhanced. The most
relevant research topics are presented below:
•
Preconditioning and convergence of iterative methods for the
solution of linear systems of equations, generalized inverses and
its applications.
•
Interior-point algorithms, active-set methods, sequential quadratic
algorithms
and

4.4.3.9
Instrumentation and Measurements - Lx
The Instrumentation and Measurement Group works in the broad domain of
Metrology. In 2012 the main topics addressed were:
•
Analogue-to-digital and digital-to-analogue conversion;
•
Measurement of electrical quantities;
•
Non-destructive testing
•
Sensors and transducers;
•
Signal acquisition and automated and telemetric measuring systems;
•
Signal processing applied to sensors and instrumentation.
Analogue-to-digital and digital-to-analogue conversion
•
Study of the uncertainty of analogue-to-digital converter test methods,
namely of the Histogram Test Method, the Random Noise Test Method
and the Sine Fitting Test Method. Consideration of different non-ideal
effects like additive noise, jitter, phase noise and harmonic distortion.
Measurement of electrical quantities
•
Design, implementation and analysis of a three-phase energy metering
device.
Non-destructive testing
•
Work in the area of non-destructive testing using eddy currents went on.
Applications were extended to determine thicknesses. Different types of
excitation currents have been used: pulsed eddy currents (PEC),
sinusoidal and poly-harmonic currents.
The use of digital signal processing algorithms to process and interpret data
provided by the sensors used in the laboratory for eddy current testing proved to
be very effective to overcome the poor performance of some of these sensors.
Significant improvements in the crack position accuracy and resolution were
obtained. Some of the crack characteristics like length and orientation are now
obtained using the measurement system developed at the Instrumentation and
Measurement Laboratory.
Support Vector Machine (SVM) has been used to material thickness classification. A
further application like the detection of corrosion inside a pipeline is being
envisaged.
Novel low-cost handheld instruments to detect cracks and other defects in a plate
of conductive material have been implemented and the prototypes are working
properly. One of these instruments uses a planar excitation coil with a giant
magnetoresistor as the sensing element and the visualization of the defect can be
depicted in real-time on an LCD display. Besides the output voltage the sensor
location can be transmitted to a PC for further processing. The other instrument is
able to measure both amplitude and phase of the sensor output voltage
(corresponding to the secondary magnetic field with the crack information) and
transmitted to the PC wirelessly to be depicted as phasors.
A new non-destructive testing technique based on speed induced currents is being
tested. The conductive material being tested moves in a time constant magnetic
field and due to the movement the induced currents in the conductor generate a
secondary magnetic field. When the current flow pattern is disturbed by the
existence of defects, variations of the magnetic field occur and information about
the defects can be assessed by measuring the magnetic field. As far as the authors
know this is an original method, that has not yet it been reported in the literature,
and presents undoubted advantages when the material to be tested is in motion
relative to the test sensor.
Sensors and transducers
•
In-depth analysis, modelling and experimental evaluation of a differential
planar eddy currents probe.
•
Progress in the interoperability of marine observatories has been carried
out.
Sensors

analogue
outputs
will
have
their
connectivity
augmented with an embedded Transducer Electronic Data Sheet, which
contains technical information to identify the sensor. Data will be
formatted according to IEEE 1451.0 standard and interoperability in
OBSEA and MBARI observatories is already a fact concerning some

Integrated Circuits - Av
The scientific activities addressed by the members of the Integrated Circuits group
from IT-Aveiro, during the year 2012 followed six trend lines: 1) energy efficient
concepts for public illumination systems; 2) Electronic design for visible light
communication systems; 3) CMOS integrated circuit design; 4) TDOA telemetry for
wildlife tracking systems, 5) high speed synchronization, 6) SAW based sensors
development and design; 7) Diamond films for thermal management of high-power
RF devices and 8) Radio astronomy methods for deep space exploration. Some of
the activities under these trend lines are the result from ongoing research projects,
as well as future project perspectives. Most of these projects have national funding
sources. The group members are currently concentrating their efforts on other
financing sources at international levels and co-operation with industrial partners.
The following description highlights the expected achievements under each of these
lines.
1. Energy Efficient Concepts for Public Illumination Systems – This topic
represents a new trend on the usual activities of this group. It departed from
the gathered knowledge on solid state lighting devices, LEDs, also explored
for other purposes. Public illumination systems are predicted to be
dominated by solid state lighting devices in the next few years. LED
technology has several advantages when compared to other illumination
devices in current use. The exploitation of these advantages and the
advancement of collaborative control strategies for these systems are
currently a hot topic for both research and industrial sectors. The activities
under this line of research started with the participation on an International
funded project, involving several participants from the European community
(project
LITES:
CIP-ICT-PSP-2008-2/238916,
still
active).
The
major
achievements under this line of research have been the dissemination of the
group activities both at national and international levels, and the direct
contact with several actors from the industrial sector that may result in
future collaborations. Future perspectives in this line aim towards the
conception of collaborative strategies, able to reduce power consumption,
and the development of a communication standard for public illumination
systems. New project proposals, building up from recent collaboration
between
the
Integrated
Circuits
group
and
the
Advanced
Telecommunications
perspectives
for
and
these
Networks
systems,
group
namely
are
the
posing
new
exploitation
of
design
sensor
networking concepts able to promote efficiency and raise new added value
services.
2. Electronic design for visible light communication systems – This line of
research has started with project VIDAS (PTDC/EEA-TEL/75217/2006). This
project addressed the deployment of visible light communication concepts
under the application of traffic information broadcasting. The reasoning
behind this project was to take profit from the LEDs that make part of most
traffic light under operation in our street, and to use them as modulating
devices, so that traffic signaling and information broadcasting can coexist in
parallel. Illumination systems are currently adopting LEDs as illumination
devices, due to their long life expectancy and low power consumption
characteristics. Using these illumination devices for both illumination and
information transmission will offer several research opportunities. One
member of this group is now leading a special interest group on visible light
communications applications on the framework of the IC 1101 COST action
on “Optical Wireless – a promising technology”. Recent collaboration
between the integrated circuits, the optics and the wireless communications
groups are now concentrating efforts on the exploitation of high speed
visible light communication links for outdoor applications.
3. CMOS integrated circuit design – This line of research results from the
gathered experience of this group on the field of integrated circuit design.
Current research efforts are focusing on the design of visible light
communication
transceivers
using
LEDs.
Topics
under
research
are
addressing energy efficiency measures for integrated circuit amplifiers
design and LED drivers able to support dimming and communication
functionalities. Under the topic of energy efficient integrated circuit amplifier
design, the main objective is to advance new design strategies able to
optimize circuit performance without impairing power consumption. The
expected outcome will be the achievement of energy efficient amplifiers.
Until now the research on this line concentrated on the analysis and
deployment methods for minimum power consumption in amplifiers. This
line of researched was initially supported by national funded project (project
EECCO: PTDC/EEA-TEL/105314/2008, terminated in October 2012). The
design of LED drivers presents several challenges, namely: efficiency
optimization, integration of dimming functions with the transmission of
signals using unconstrained modulation schemes, and handling large
currents - especially for high power LEDs often used for illumination
purposes.
4. TDOA Telemetry for Wildlife Tracking Systems – Traditional telemetry
solutions
for
wildlife
tracking
and
surveillance
resort
to
two
main
approaches: RF tracking systems, and GPS based data loggers. RF tracking
systems are crude and require human intervention. On the other end, GPS
based data loggers have the ability to be very accurate, but they are also
very expensive. Moreover, GPS based systems are not a good choice for
small animals (as for instance the case of small birds). This has led the
Integrated Circuits group members to advance a new solution able to deliver
accurate position information, and to reduce the size of the identifiers. This
solution is based on TDOA (Time Difference Of Arrival) measurements. Initial
research as demonstrated the feasibility of our intents. A close cooperation
was also established with researchers from Biology as well as industry
(Biotrack).
5. High speed synchronization - A recently concluded PhD thesis on the field of
high speed synchronization is now opening new collaboration opportunities
with
INESC-ID.
A
FCT
project
proposal
building
up
concepts
on
synchronization, clock distribution and timing uncertainty, was submitted.
This project, will analyze the impact of clock management and distribution
resources on on-chip PSN, in FPGAs. The main goal is to determine under
what conditions such resources can be used without affecting the device's
overall performance and to what extent this can affect its dynamic
performance. This knowledge can later be used to develop techniques for
designing loosely synchronous digital circuits in FPGAs, maximizing their
available performance. On the other hand, it may allow the future
development of routing resources in FPGAs that enable more efficient
implementation of systems Globally Asynchronous Locally Synchronous
(GALSs).
6. SAW Based Sensors Development and Design – Under this line of research
the main objective is to develop SAW based sensors, using diamond film
layered structures. Surface acoustic wave devices are wireless and passive
versatile devices that can be used as sensors or as RFID tags. Diamond films
are especially interesting due to their resilience to adverse conditions and
can be deposit on the SAW devices to protect them from hazardous
operating conditions. This line of research resulted from the cooperation of
the Integrated Circuits group with researchers from the Mechanical
Engineering department at the University of Aveiro. The activities under this
line of research are under the framework of a national funded project
(project JISIS: PTDC/EEA-TEL/104004/2008). Work will proceed in 2013
also with financing from (SI-IDT) QREN under project Seesaw (nº 21634),
involving
two
members
of
the
team.During
this
work,
piezoelectric
substrates and devices will be coated with diamond films. A proper read-out
unit will also be implemented.
7. Diamond films for thermal management of high-power RF devices – GaN is a
material widely used for high-power electronic applications. However,
increasing operating frequencies and shrinking of devices pose self-heating
problems that limit the performance of devices and further development of
GaN technology. Diamond films have an excellent thermal conductivity and
can be combined with GaN technology to improve heat extraction from the
devices, increasing their lifetime and improving their performance. This work
aims at coating the GaN devices with diamond films, assuring an intimate
thermal contact between the devices gate and the film.
8. Radio astronomy methods for deep space exploration - Much of the 2012
year was devoted to activities of building the Industry Consortia for the
Request of proposal of the SKA Project Execution Plan towards PreConstruction Phase. These activities unfolded through the release on White
papers and Reports of the PrepSka Consortium by March 2012. These
papers versed on Procurement and Industry Involvement, Governance and
Legal Framework and on SKA System Design, in a continuity of previous
2010-2011 activities. Two major workshops were organized to focus on the
Request
for
proposals
for
Pre-Construction,
and
establishment
of
International Consortia : on Signal and Digital transport/ Synchronization &
Timing, Power, and Mid Dense Aperture Arrays in the context of SKA
Advanced Instrumentation Program; through these Consortia we established
strong partnership and presence of national industries : Nokia Siemens
Networks
Portugal,
LOGICA
EMSA,
Martifer
Solar
and
the
National
Competivity Poles TICE and EnergyIn. The Power of Mega
Science
Infrastructures was held in Moura, by June 2012 to explore Current energy
consumption projections for SKA and recent experiences from pathfinders
and precursors (LOFAR, ASKAP, Meerkat) reveal that an important part of
the life cycle cost of these large scale radio astronomy projects will be
power. Energy transport infrastructure and generation to supply the
electronics and the associated cooling are key factors. This last aspect has a
direct impact on the system sensitivity, since any potential power caps
would limit performance of frontend Low Noise Amplifiers. Thus, power
generation and power efficiency (innovative form of passive cooling) become
a paramount ingredient of these projects. This workshop reviewed current
R&D trends, industry forecasts for solar energy options and experiences that
may respond to the challenges set by Mega Science Infrastructures and in
particular by the Square Kilometer Array project. As part of these activities,
improving the collaboration with Martifer Solar and EnergyIn - The national
Pole on Sustainable Energy Systems towards the greening of the SKA
project, was continued. The BIOSTIRLING FP7 proposal was approved and
shall start by March 2013 and provide a test bed solution for the SKA
prototypes in Moura, Portugal, thus constituting the first EU funded SKA
Power project, with international validation on national soil. We organized,
under the 8th Partnership EU-Africa Forum on ICT, the SKA PT Day
Workshop, held in Lisbon by 30th November 2012, an event to present the
Square Kilometer Array (SKA) and radioastronomy to the European
Community, Policy Makers & African Collaborators. The Square Kilometer
Array is a transformational radioastronomy project, an ultimate and
powerful ICT machine precursor to Future Internet technologies fed with
Green Energies offering a great societal change promise. Together with the
African VLBI Network, the SKA will provide a leverage infrastructure for the
Space Galileo project in Africa and expand global Space Exploration
capabilities. These aspects are core to the EU HORIZON 2020 roadmap.
a. As part of the PhD work of Miguel Bergano, supervised work on the
X-band
cross
complex
correlator

accomplished. It was designed and tested a VHDL algorithm for FGPA
integartion. This new digital backend comprises a base-band complex
cross-correlator outputting the four Stokes parameters of the
incoming polarized radiation to be used in Space Science surveys.
The FPGA board has a 1GHz bandwidth, processing 32 Gb/sec of
data. A variation of the correlator was proposed for the Moon Lander
Mission, as part of the ESA MESSI (Moon Environment SDR
Spectrograph) payload. This was a collaboration with CICGE-U. Porto
and Tekever as Prime contractor. MESSI was designed to measure
potential Moon ionospheric cut and the radioelectric properties of the
Moon crater environment.
b. As outreach activities, a 3-meter SRT (Small radioTelescope) was
installed in Pampilhosa da Serra. This SRT shall be a node of the
European Hands on Universe Project and part of the first
International network of antennas for operation by schools. The
antenna operated a 1.4GHz radiometer and is remote controlled

technologies are opening up new opportunities for utilization of
alternative
energy
resources
for
telecommunications
(TLC)
applications. The equipments used in TLC have strict specific

stand-alone power systems (SAPS) is increasing and the value of
alternative power solutions is becoming more apparent. Considering
this, the main general objectives of this research program are:
• The investigation of the new available technologies for the
generation
and
storage
of
energy
for
TLC
applications;
• The development of a SAPS capable of self-diagnosing power
converter faults and, in case of a failure occurrence, to keep its
normal operation, although with a reduced performance.

Title
Kernel Method Applied to Non Destructive Evaluation
Funding
IT
Descript.
Throughout the world, engineers and technicians are working
together finding cracks and other anomalies to prevent expensive
failures. The increasingly important role of nondestructive testing in
public security and safely technology development promote new and
innovative methods to be developed and already known methods do
be enhanced. Eddy Current Testing (ECT) is one of the most
established nondestructive structure evaluation technique that
enables defect detection and material condition monitoring with high
sensitivity and reliability. Within this method the volume distribution
of the material conductivity is determined by inducing eddy currents
inside the conductor under test and measuring the magnetic field
produced by those currents [6]. ECT is used with electrically
conductive materials for the measurement of the thickness of
metallic plates [7] or non-metallic coatings or metal substrates,
estimation
of electrical
conductivity or magnetic permeability
distribution, corrosion detection [8] and the determination of
surface or subsurface defects [9]. However, regarding safety and
economic efficiency assessment, defects are still the main concern
and
with
the
improvements
on
understanding
the
facture
mechanics, the detailed geometric characterization of the cracks,
still an open problem, became the target of the research in the
area. One disadvantage of this type of method is related to the
inevitability of well qualified and experienced technicians to perform
the tests since, in spite of its implementation simplicity, data
produced by eddy current based equipment are among the most
complicated to interpret. These factors together motivate the
project objectives: to implement new and better measurements
with both novel instrumentation and embedded artificial intelligence
to automate the interpretation of the various imaging data streams
in order to determine surface and subsurface defects shape and size
[10].
With eddy currents nondestructive evaluation, the dimensions of
defects are retrieved by inversion of the measured signals. Since
the physical model of the problem is often complicated and nonlinear, the inversion model is ill-posed and it’s solution always a
challenge. Within this project an original strategy based on the
current lines distribution is proposed. The idea is to assess the
current density perturbation caused by the defects through a bidimensional map of the magnetic field components on the surface of
the material to be tested, obtained experimentally. This current
density can be represented as a composition of magnetic dipoles.
The field of the single magnetic field dipole will be the kernel of the
transformation to be used in the inversion process. Measurements
are
taken
using
electromagnetic
sensors
based
on
giant
magnetoresistive (GMR) effect. GMRs extend the application field of
eddy current non destructive evaluation methods since they
measure the magnetic field directly and their sensitivity is equal for
all
working
frequencies,
allowing
better
performance
than
conventional probes for low-frequency applications as, for instance,
when detecting defects deep buried in multilayered structures.
Besides, these sensors are far more sensitive than those used in
current commercial equipment [11] and the output signal signal-tonoise ratio is high enough to apply regularization methods to extract
information.
It is our goal to develop a competitive automated system to be
subsequently exploited and used in the industry. This project
besides its technical and scientific objectives is also focused on
promoting nondestructive evaluation issues to young researchers. It
is a multidisciplinary field of study that embraces issues like: (1)
technology development; (2) image processing and recognition; (3)
modeling
and
algorithms.
In
Portugal
there
are
very
few
competencies within the nondestructive testing knowledge area in
spite of the abundance of industrial relevance for them and as a
result Portugal is losing competitiveness in a 600 million global
market.

NANOPEPS
Micro- and Nanopatterning of cross-linkable electro-active polymers
by spin-coating
Funding
Descript.
FCT/PTDC
This project deals with the optimization of organic electronic
devices, namely photovoltaic cells (PV), light-emitting
diodes
(LEDs) and optical chemical sensors, through the provement of the
organic film morphology and functionality using a low-cost, simple,
and innovative method of patterning at the submicrometric or the
nanoscale.
Our group was recently pioneer in exploring a simple and low-cost
method to prepare patterned films at the submicrometric scale
using cross-linkable electroluminescent polymers also synthesised in
our group. In principle, the method should be scalable to large
substrates and to a broad range of different classes of conjugated
polymers. Basically, it consists on controlling the phase separation
occurring during the deposition of a solution containing a cross-
linkable electro-active polymer and an «inert» polymer, on a
substrate, by spin coating. The main original characteritsic of this
approach
is
that
the
cross-linked
film
is
resistant
against
dissolution, enabling that multilayer devices may be fabricated
utilizing low cost solution techniques. This project proposes i) to
synthesise
new
cross-linkable
semiconducting
polymers
with
chemical properties designed for specific applications; ii) to extend
and to explore the patterning method to those materials to obtain
film morphologies tuned for specific applications iii) to fabricate
efficient devices based on such films. The target devices are:
- PV cells. Semiconducting polymer based-films where electrondonor and -acceptor materials are segregated forming vertical
domains (relative to the electrodes) and these are separated from
less
than
20
nm
represent
the
optimal
film
morphology, because it minimizes losses in the charge generation
and transport to the electrodes processes. By preparing adequate
crosslinkable polymers and using the referred patterning method,
we aim at tuning the column dimensions (of columnar films) or
porous diameter (of porous films) to obtain ideal nanostructured
polymer scaffolds, where the complementary component (donor or
acceptor) can afterwards be deposited filling the empty spaces. The
resultant arranjement of the two interpenetrating layers should
approach
the
“ideal”
morphology
for
OPV
cells.
- Optical Chemical Sensors. Fluorescent semiconducting polymers
have
shown
an
amplified
response
in
chemosensing
processes. We intend to functionalize the polymer nanopatterned
film to recognise selectively a specific target molecule which acts as
a fluorescence quencher, generating an optical sensor. Since
nanostructures have a huge surface/volume ratio, an even higher
sensitivity is expected. Examples of analytes to investigate are
fluoride, cyanide, and iodide anions resultant from toxic gases, and
metal
ions
such
as
Al3+,
Pb
2+,
and
Ag+.
- LEDs. The most efficient organic LEDs are based on multilayered
devices comprising both charge transport layers and emissive layers
between the electrodes. Besides showing reasonable efficiencies,
such values are still well below the predicted maxima. One approach
for optimization, nearly unexplored so far, consists on the use of
nanopatterned
hole-transport layers to increase the contact area for charge
transfer to the emissive layer. Also, there have been reports
demonstrating higher emission efficiency in nanopatterned films, for
which nanopatterning of the emissive layer represents another
approach to optimize LEDs.

SolarNHyMat - Nanostructured Hybrid Materials for Solar Cells
Funding
FCT/PTDC
Descript.
The â€œSolarNHyMatâ€ project aims to foster essential progress
in the performance of organic solar cells devices by covalent
incorporation of acceptor molecules on the walls of mesoporous
silica nanostructured materials and encapsulation of the donor
polymers on the pores of those same silica materials. The key
scientific objectives of the â€œSolarNHyMatâ€ project will be (i)
alignment of the acceptors (on the walls) and donors (on the
pores), (ii) maximize the interfacial area and the donor:acceptor
contact, (iii) isolation of the polymer chains into nanoscale domains
leading to a confinement effect, (iv) charge stabilization conduction
along individual chains with spontaneous formation of a gradedindex waveguide, and (v) circumvent oxygen interference. The
expected results for the â€œSolarNHyMatâ€ project taking into
account the above objectives are (i) avoid phase segregation and
minimize the recombination process, (ii) improve charge separation
and increase carrierâ€™s mobility, (iii) no interchain hopping events
would be required, (iv) improve gain and reduce loss, and (v)
enhance the long term stability.

Optical Measurement of Guided Acoustic Waves in Solid Media
Funding
IT
Descript.
The coupling of ultrasound waves into solid media on a material
surface point followed by the wave detection on another point can
be used to infer about the wave propagation conditions. The wave
suffers reflections on the material boundaries, but is attenuated or
diffracted on existing material discontinuities. It is possible to obtain
valuable information about material defects by an accurate analysis
of the wave propagation conditions. In this project we intend to
apply the ultrasound method to establish an experimental method
of defects detection inside solid structures whose structural health
monitoring is of great importance. This is the case of the aircraft
structures, the liquid or gas pipelines in nuclear power plants or
other containers subject to high pressures. To our knowledge, the
most important inspection task at this time is the assessment of
possible internal defects inside the stainless steel containers of the
International Thermonuclear Experimental Reactor (ITER).

SearchCol: Meta-heuristic Search by Column generation
Funding
FCT/PTDC
Descript.
Many relevant practical problems can be modeled as combinatorial
optimization problems (COPs). Examples are the definition of routes
for vehicles, schedules for machines, or the dimensioning of
telecommunication networks. Meta-heuristics (MHs), such as tabu
search or genetic algorithms, are the most successful methods in
providing good-quality solutions in reasonable amounts of time for
large-size instances of several COPs. The aim of this project is to
propose
a
new
MH,
entitled
Search
by
Column
generation
(SearchCol), for COPs. SearchCol algorithms will be applied in
specific
problems
from
four
areas:
production
planning
and
scheduling, telecommunications, forest management, and cutting
and packing. The main distinctive feature of SearchCol is that its
ingredients
(such
as
construction
of
solutions,
neighborhood
structures, or crossover operators) are based on column generation
(CG).
We aim at proving that a suitable search strategy (provided by the
hybrid MHs framework) taking advantage of decomposition exact
methods (CG) quickly leads to high-quality solutions for NP-hard
COPs. The evidence is that CG provides tight lower bounds (in
minimization problems) on the optimal value and that the columns
belonging to the restricted master problem define a search space
where high-quality solutions exist. The drawbacks of standard MHs
(the lack of ameasure of the quality of the solution obtained and the
lack of a well defined stopping criterion) are overcome in SearchCol
since the lower bound provided by CG is available.
