Sum-up of my teachning and research activities

Responsibilities

- Co-head of Communications department of IETR since January 2012
- Elected member of IETR Laboratory Committee
- Member of IETR Scientific Committee
- Member of PhD Committee of Doctoral School MATISSE for "electronics" topic
- Elected member of CentraleSupelec Scientific Committee
- Member of MEC Academic Committee (Mahindra Ecole Centrale), Hyderabad, India

Teaching activities

My teaching activities focus on wireless communication systems in general, from phenomena understanding (propagation and multi-path, signal processing and digital communications), until implementation in both analogue (low frequency analogue electronics, radio frequency analogue electronics) and digital (design methodologies, digital architectures for frequency translation) domains. I am teaching at both undergraduate and Master levels. I am also supervisor of several PhD students.

Reseach activities


My research activities have been concerned since 1999 with the study of Software Radio systems and have been extended towards Cognitive Radio systems since I have been in the SCEE research team of SUPELEC school and IETR CNRS lab (UMR 6164).
My research on cognitive radio and software radio focus on:
- the design of multi-standards software radio equipments,
- management architectures for cognitive radio equipments,
- decision making for cognitive radio.

Cognitive Radio

A Cognitive Radio (CR) is based on a Software Radio or a Software Defined Radio (SDR) that provides the flexibility necessary to adapt to its environment. In addition to the flexible platform, a cognitive radio should also inegrate sensing and decision making means in order to be able to make all 3 steps of the simplified cognitive cycle : sense, adapt, reconfigure. Then a CR equipment is made of:
- flexible signal processing,
- flexible electronic platform (probably heterogeneous processing),
- sensors of many different kinds,
- a plurality of decision algorithms,
- something to mak all this work together in a coherent way: a management architecture (we propose HDCRAM).

SDR systems design

SDR architectural studies are still an open area. Several approaches are considered in the SCEE laboratory. We particularily address high level design approaches. Two reasons exist for that. First, CR and SDR design is becoming so complex, with so many uses cases that you can not anymore contempt on current design tools and methods to address the complete design space. Second is that starting the design at a higher level enables to stay as much as possible independent from the HW implementation so that the maximum of your design is valid whatever the implementation target.

Previous experience

Researcher in the European research lab of Mitsubishi Electric for digital communications during 6 years, from February 1999 to Febraury 2005. I worked there on:
- software radio design,
- implementation of radio processing in digital domain,
- reconfiguration,
- intensive parallel processing,
- hardware architectures and platforms.
