Digital Compensation for Analog Front-Ends (eBook)

Fran?ois Horlin recently became a Professor at the "Université Libre de Bruxelles" (ULB), Brussels, Belgium. Prior to this he worked at the Wireless Research group of the Inter-university Micro-Electronic Center (IMEC), Leuven, Belgium, as a senior researcher, leading the research activities on digital signal processing for broadband communications. His fields of interests have always been in digital signal processing (DSP), mainly for high bit rate multi-user communications. He received an electrical engineering degree and Ph.D. from the "Université catholique de Louvain" (UCL), Louvain-la-Neuve, Belgium, in 1998 and 2002 respectively. André Bourdoux is a senior scientist in the Wireless Research group of the Inter-university Micro-Electronic Center (IMEC). He currently coordinates the research on millimeter-wave communications, helping antenna specialists, analog designers and DSP specialists to align their research efforts. Before joining IMEC, he was with Bats, Belgium, working first as an R&D engineer, then as a system engineer, mainly on radar systems. He received an MSc in Electrical Engineering (specialisation in micro-electronics) in 1982 from the Université catholique de Louvain (UCL), Belgium.
