Green Software Defined Radios

Liesbet Van der Perre: received the M. Sc. Degree in Electrical Engineering from the K.U.Leuven, Belgium, in 1992. The research for her thesis was completed at the Ecole Nationale Supérieure de Telecommunications in Paris. She graduated summa cum laude with a PhD in electrical engineering form the same university in 1997. Liesbet earned an award from IBM in 1986, and she received a study-visit scholarship for study in the United States from the Fina Maecenas Foundation.

Her work in the past focused on radio propagation modeling, system design and digital modems for high-speed wireless communications. She was a system architect in IMEC's OFDM ASICs development, which was nominated as one of the IEEE International Solid State Circuit Conference's (ISSCC's) 'Best of 50 Years' papers. Consequently, she was the project leader for IMEC's low power Turbo codec. Currently, she is the scientific director of wireless research group in IMEC's, comprising teams of researchers in the fields of digital baseband solutions, RF front-ends, cross-layer optimization, mixed-signal design technologies, and ultra low power radios. She's the project leader for the digital baseband Software Defined Radio, and a public speaking coach for IMEC staff. Also, she was a part-time professor at the University of Antwerp, Belgium, till 2004. She's an author and co-author of over 150 scientific publications published in conference proceedings, journals, and books.

Jan Craninckx: obtained his Ms. and Ph.D. degree in microelectronics summa cum laude from the ESAT-MICAS laboratories of the Katholieke Universiteit Leuven in 1992 and 1997, respectively. His Ph.D. work was on the design of low-phase noise CMOS integrated VCOs and synthesizers, where he was a pioneer in RFCMOS design. From 1997 till 2002 he worked with Alcatel Microelectronics (now part of STMicroelectronics) as a senior RF engineer on the integration of RF transceivers for GSM, DECT, Bluetooth andWLAN. Since 2002 he is a principal scientist in the wireless research group in IMEC (Leuven, Belgium) where his research interests are in the design of RF transceivers for software defined radio (SDR) systems. Dr. Craninckx has authored and co-authored more than 60 papers, several book chapters and has published one book in the field of analog and RF IC design. He is the inventor of 10 patents, and is a member of the Technical Program Committee for both the ISSCC and ESSCIRC conferences.

Antoine Dejonghe: received the M. Sc. Degree in Electrical Engineering (summa cum laude) and the Ph.D. degree from the Université Catholique de Louvain (UCL), Louvain-la-Neuve, Belgium, in 2000 and 2004, respectively. He was with the Communications and Remote Sensing Laboratory of UCL from 2000 to 2004, as a Research Fellow of the Belgian National Fund for Scientific Research (FNRS). Since 2004, he is Senior Researcher in the Wireless Research Group of the Inter-university Microelectronics Center (IMEC), Leuven, Belgium. His work in the past focused on digital communication system design, with a special emphasis on iterative detection and decoding schemes relying on the so-called turbo principle. He is currently carrying and coordinating research activities in the field of cross-layer optimization for energy-aware multimedia wireless communications, building on SDR-based baseband engines and reconfigurable analog front-ends. He is also looking at the extension of these concepts to cognitive radio systems. Antoine Dejonghe is an author and co-author of over 35 scientific publications.
