Cedric Dehos joined CEA Leti in 2003 after graduation from ESIEE Paris (Ing. Dipl. and M.Sc.) in Telecommunication and Signal Processing. Since then he has been involved in system level design of complex RF and digital base band circuits, including RF behavioral modeling, architecture design and specification, system simulation and base band signal processing. His interest included Ultra-Wide Band systems, digital compensation of RF imperfections, antenna beamforming. Since 2006 he has been involved in various mmw developments in CMOS or BICMOS technologies, including 79GHz Short Range Radar, Wireless HD and WiGig. In 2011 he led Leti mmw designs and began moving the developments towards 5G small cells and short range chip to chip communications.
