Current post-graduate students

Luís Nero Alves - PhD, currently a teacher at Escola Superior de Gestão e Tecnologia, in Instituto Politécnico de Leiria.  Thesis: High-Bandwidth Current-Mode Analogue Circuits. The thesis aims to research efficient techniques for improving bandwidth (including also noise aspects, due to dynamic range considerations) in current mode circuits, fundamentally for telecommunication applications. 

Miguel Madureira - PhD, currently a researcher at Instituto de Telecomunicações, in Aveiro. Thesis: Design of Wide-Band Integrated Receivers, co-supervised by Prof. Paulo Monteiro. The thesis aims to develop new techniques for the design of wide-band receivers, covering frequencies above 10GHz, fundamentally in CMOS technologies. Work funded by Praxis XXI.

Victor Marques - PhD, currently in Portugal Telecom Inovação, in Aveiro. Thesis: Multimedia services for heterogeneous networks, co-supervised by Prof. Manuel de Oliveira Duarte. This thesis aims to analyse critical aspects for the implementation of multimedia services, from the operator point-of-view, in heterogeneous environments, covering aspects as technologies, adaptation layers, and quality of service provision. 

Carla Paiva - MSc., currently in Portugal Telecom Inovação, in Aveiro. Dissertation: Quality of service in IP multicast networks. The objective of this work is the study of quality of service issues in multicast networks, focusing on existing equipment, and on network-provider views.

Américo Mendes - MSc., currently a teacher at   Escola Profissional de Trancoso, in Trancoso. Dissertation: Dedicated implementations of the Viterbi algorithm. The objective of this work is the development of virtual components that support the Viterbi algorithm, fully configurable, and that allow the prioritisation of different system metrics (mostly speed vs resources used), in function of the overall constrains for the design.

Miguel Osório - MSc, currently at Siemens Portugal, in Lisboa. Dissertation: Implementation of IP over new physical layers. This work analyses implementation techniques optimised for IP-support over new physical layers, focusing in particular in the development of a virtual component for an IP-interface for SDH networks. 

Lina Brito - MSc. currently a teacher at Universidade da Madeira. Dissertation: Quality of service (IP) in mobile networks. The objective of this work is the development of quality of service architectures applicable to different mobile networks, both local area networks (notably 802.11x), and cellular public networks (specially  UMTS).

João Santos - MSc., currently on Portugal Telecom Inovação, in Aveiro. Dissertation: Quality of Service over Mobile Heterogeneous Networks. This work will develop environments for the provision of quality of service in high heterogeneity situations, most notably between networks and concepts existing in current cellular networks (GPRS) and next generation networks (UMTS).

Pedro Gonçalves - MSc., currently a researcher at Instituto de Telecomunicações, in Aveiro. Dissertation:  Implementation of a Quality of Service Management System for IP Networks. This work will develop a Bandwidth Broker, able to manage quality of service aspects in the access network for heterogeneous environments.

Victor Jesus Silva - MSc., currently an entrepreneur in Porto. Dissertation:  Quality of Service in Mobile Autonomous Networks. This work will study problems associated with the implementation of Quality of Service mechanisms in mobile autonomous networks (manet).

Maria de Fátima Gonçalves - MSc., currently working in SCTP, Porto. Dissertation:  New signalling mechanisms for Quality of Service in Mobile Networks. This work will develop new signalling mechanisms for Quality of Service, in accordance with the framework proposed in the IETF nsis work group.

Final year projects (2002-2003)

Demonstrator of heterogeneous mobility - This project aims to implement a trial network supporting heterogeneous mobile environments, including quality of service aspects. The demonstrator will support Ethernet, 802.11, and WCDMA (i.e. UMTS), running the IPv6 protocol, and, amongst others, IPSec, DIAMETER, Mobile-IP, SNMP, and COPS. For such, it will use methodologies and equipment developed by the project Moby Dick. This work is supported by Portugal Telecom Inovação.  Project web page: http://mobydick.av.it.pt

Projects

Intervention Areas

My interests can be divided according with the areas:

• Mobile communications networks and systems, in particular infrared systems. 
  In general terms, mobile networks. 
• Quality of service in communication networks. 
  
• Timing aspects in high-speed digital electronics, in particular clock distribution and synchronization systems. 
  
• Design of receivers for digital communications
  On general terms, digital communication receivers, covering aspects from front-end design to synchronization aspects. In particular, both dynamic range and bandwidth aspects have been exploited through different project techniques. 

Current projects

Currently involved in the organization of IST Mobile Communications Summit 2003, to take place in Aveiro, June 2003.

Currently involved in the project IST 2000-25394 Moby Dick, under contract by Portugal Telecom Inovação. In this project, I am fundamentally involved with the problems of quality of service in mobile heterogeneous networks. 

Currently involved in the project IST 2001-32620 MATRICE. In this project, I am fundamentally centred in the problems of dynamic channel allocation, in function of quality of service signalling coming from the IP layer, and in evaluating the implementation of these mechanisms in real systems.

Currently involved in the project SIRAC “Sistema Integrado para Redes de Acesso da Próxima Geração (Integrated System for Next Generation Access Networks)”, financed by Plano Operacional de Economia (Economics Minister), and coordinated by Portugal Telecom Inovação. I am the responsible for the implementation of an RPR module (Resiliente Packet Ring, IEEE 802.17) for 622Mb/s+ SDH systems.

Currently involved in the internal project ClockSpeed, which aims fundamentally to analyse new mechanisms and circuits for clock distribution networks inside complex digital systems. 

Currently involved  in the activities associated with a protocol with Empresa Nacional de Telecomunicações, about developments of electronics for communication systems.
