Lajos Hanzo has been with the Department of Electronics and
Computer Science, University of Southampton, UK, since 1986 where
he holds the Chair in Telecommunications. He received his degree in
electronics in 1976 and his doctorate in 1983. During his career in
telecommunications he has held various research and academic posts
in Hungary, Germany and the UK. Lajos is a Fellow of the IEEE and
the IEE as well as an IEEE Distinguished Lecturer. He has
co-authored 11 books on mobile radio communications, published over
500 research papers and been awarded a number of distinctions.

Clare Somerville received M.Eng and Ph.D degrees in
Electronic Engineering in 1995 and 1999, respectively, from the
University of Southampton. From 1995 to 1998 she performed research
into low bit rate speech coders for wireless communications.
Following a spell of research with the Global Wireless Systems
Research department, Bell Laboratories, Swindon, U.K, she moved to
PicoChip in Bath, UK. Her current research involves real-time
services over wireless networks with a packet air interface.

Jason Woodard received an MA in Physics from the
University of Oxford in 1991, then an MSc in Electronics and a PhD
in Speech Coding from the University of Southampton in 1992 and
1995 respectively. From 1995 to 1998 he worked as a Research Fellow
at the University of Southampton, researching error correction
coding, especially turbo codes. In 1998 he joined the Wireless
Technology Practice at PA Consulting Group in Cambridge. At the
start of 1999 he was transferred from PA to UbiNetics Ltd, where he
is responsible for the development and implementation of bit rate
processing algorithms, including turbo codes, for 3rd Generation
mobile communications products.
