5 Research
During my three years of thesis at Grenoble-Image-Speech-Signal-Automatics Lab (GIPSA-lab), Department
of Images and Signals (DIS), I worked on channel estimation and equalization for a OFDM high speed
mobile receiver, under the supervision of M. Laurent Ros and Ms. Geneviève Jourdain (died in October
2006). This work concerns the systems of radio communication and broadcasting such as (WIMAX, WIFI,
DVB-H, ...).
Durant three months (1 september to 30 november 2009), I have been working as a research engineer
in Telecommunications at CNRS - Univeristy of Lille 1, in Laboratory of the Institute of Electronics, Microelectronics
and Nanotechnology (IEMN), Group Telecommunications, Interferences and Electromagnetic
Compatibility (TELICE). I extended my working of thesis from single antenna (SISO-OFDM) to multiantenna
(MIMO-OFDM), under the supervision of M. Eric Simon and Ms. Martine Liénard (Professor at
the University of Lille 1 and Team Leader Telecommunications in the Group TELICE). This work has
been carried out in the framework of the CISIT (Campus International sur la Sécurité et Intermodalité des
Transports) project and funded by the French Ministry of Research, the Region Nord Pas de Calais and the
European Commission (FEDER funds).
Since december 2009, I make a post-doc at France Telecom - Orange on the Infrastructure pseudo-cell
of the wireless sensor network in urban area, under the supervision of M. Benoît Miscopein.
My research interests include OFDM, MIMO, time-varying channel, channel estimation and synchronization
in urban and rural areas and in submarine areas, GSM, sensor network.
