Biography

L. H. Charles Lee received the Ph.D. degree in electrical engineering from University of Manchester, England, in 1987. In 1987 and 1988, he was appointed lecturer at the Hong Kong Polytechnic. From 1989 to 1991, he was a staff member of the Communications Research Group, Department of Electrical Engineering, University of Manchester, England, where he was involved in the design of channel coding and interleaving for the Pan European GSM digital mobile radio system. Currently, he is with the Department of Electronics, Macquarie University, Sydney, Australia. He has been involving in the under-graduate and post-graduate teaching of communication theory and error-control coding, and the design of channel coding and modulation for an indoor wireless LAN system. He is the author of Convolutional Coding: Fundamentals and Applications, Artech House, 1997 and Error-Control Block Codes for Communications Engineers, Artech House, 2000. His current research interests include theory and applications of error-correcting codes, and digital communications.
