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.
