Background

In 2000, I received my Engineering diploma from the National Institute of Applied Sciences (INSA) of Rennes, France, and my Master degree in Electronic and Electrical Engineering from Strathcyde university, Glasgow, Scotland. 
In 2003, I received my Ph.D degree in Electronic and Electrical Engineering from the National Institute of Applied Sciences of Rennes. My Ph.D. advisors were Profs. P. Siohan (France Télécom R&D) and J. Ronsin (INSA). I was involved in Joint Source Channel Coding of Variable Length Codes with Turbo Codes.

Thanks to a CIFRE convention between France Télécom R&D and the INSA of Rennes, from 2000 to 2003 I was a research engineer in France Télécom R&D, Rennes, France. During this period I also had the opportunity to spend six monthes in the Image, Video & Multimedia System laboratory in Stanford university, USA.

I am currently a post-doc fellow at INRIA/Rennes (Temics team) where I am studying Joint Source Channel Coding with Arithmetic Codes.

Research Activities

My works essentially deal with Joint Source Channel Decoding (JSCD). The aim of JSCD is to take advantage of the source coder's residual redundancy, in system decoders.

In my thesis, we study JSCD with Huffman codes and we evaluate its performance in new contexts. To do so, we mainly concentrate ourself on a JSCD technique [Guivarch, Carlach, Siohan, DCC 2000]. This technique, detailed in a formal way, aims to improve the global decoder by keeping a one to one relation between the channel decoding trellis and the VLC tree. Then, comparisons with alternative JSCD methods are realized. JSCD method's performances are next estimated on the Rayleigh channel, and on UMTS channel models. Finally, we propose a JSCD method's validation on video sequences. By another way, a study on distributed source coding has been realized in parallel. We propose, a compression technique that uses VLC, as an alternative to the usual solutions that are based on channel codes.
Since the beginning of my post doctorat, I am studying JSCD with arithmetic codes.
