Cédric Herzet

Short biography

Cédric Herzet was born in Verviers, Belgium in 1978. He received the Electrical Engineering degree and the DEA in Applied Science from the Université catholique de Louvain (UCL), Louvain-la-Neuve, Belgium, respectively in 2001 and 2003. His graduation thesis concerned multiuser turbo receivers for WCDMA (Wideband Code Division Multiple Access) transmissions. He received his Ph.D. degree in April 2006. The topic of his thesis was the design and the study of tractable synchronization algorithms for "code-aided" synchronization of digital receivers.

After his thesis, he spent 5 months in the Ecole Normale Superieure de Cachan, France, where he dealt with the derivation of estimation lower bounds for communication problems

He is currently at the university of California in Berkeley for a postdoctoral stay.

Research

My research interests are in the fields of communications and signal processing theory. So far, I have been interested in the following topics of research.

During my thesis, I focused on the problem of designing receivers able to deal with uncertainties about the transmission model. More specifically, I considered systems operating at very low signal-to-noise ratio, and having to deal with uncertainties about the synchronization parameters. I have proposed several theoretical frameworks enabling to derive code-aided "turbo synchronizers". The proposed approaches are cast within the frameworks of powerful signal-processing tools (Expectation-Maximization algorithm, gradient methods, Sum-Product algorithm) and allow performance very close to the Maximum-Likelihood bound.

I have also considered the problem of assessing and predicting the performance of estimation algorithms. During my stay at the Ecole Normale Superieure de Cachan, I derived Cramer-Rao bounds associated to synchronization problems. During my thesis, I proposed methodologies to predict the performance (estimation mean square error, speed of convergence) of iterative estimation algorithms.

Currently, my research is in the field of multi-point communication systems. More specifically, I am studying coding schemes and decoding algorithms which are suitable for multi-point communication systems.
