Lajos Hanzo, Fellow of the royal Academy of Engineering (FREng), received his Master degree in electronics in 1976 and his doctorate in 1983. In 2004 he was awarded the Doctor of Sciences (DSc) degree by the University Southampton, UK. During his 28-year career in telecommunications he has held various research and academic posts in Hungary, Germany and the UK. Since 1986 he has been with the Department of Electronics and Computer Science, University of Southampton, UK, where he holds the chair in telecommunications. He has co-authored 10 John Wiley/IEEE Press books totaling about 8000 pages on mobile radio communications, published in excess of 500 research papers, organised and chaired conference sessions, presented overview lectures and been awarded a number of distinctions. Currently he is managing an academic research team, working on a range of research projects in the field of wireless multimedia communications sponsored by industry, the Engineering and Physical Sciences Research council (EPSRC) UK, the European IST Programme and teh Mobile Virtual Centre of Excellence (VCE), UK. He is an enthusiastic supporter of industrial and academic liaison and he offers a range of industrial courses. Lajos is also an IEEE Distinguished Lecturer of both the Communications Society and the Vehicular Technology Society as well as a Fellow of both the IEEE and IEE.

Currently, he is continuing his research as a postdoctoral research fellow at the University of Southampton U.K. His research interests are mainly in adaptive coded modulation, channel coding, turbo coding, space-time coding and joint source and channel coding. He published numerous papers in this field.

Thomas Keller studied Electrical Engineering at the University of Karlsruhe, the Ecole Superieure d'Ingenieurs en Electronique et Electrotechnique, Paris, and the University of Southampton. He graduated with a Dipl.-Ing. degree in1995. Between 1995 and 1999 he was with the Wireless Multimedia communications Group at the University of Southampton, where he completed his PhD in mobile communications. His areas of interest include adaptive OFDM transmission, wideband channel estimation, CDMA and error correction coding. he recently joined Ubinetics, Cambridge, UK, where he is involved in the research and development of third-generation wireless systems. Dr. Keller has co-authored two monographs and about 30 various research papers.
