About this course

This 3-day short course will focus on modern receiver design, including signal processing architectures, synchronisation algorithms and the inclusion of iterative (i.e. turbo) decoding methods in receiver processing. We will assume basic knowledge of digital communication techniques and will describe algorithms used for modern modulation, coding and multiple access methods. The course describes the underlying approaches used to realise terrestrial and satellite communications standard such as 3G (UMTS), WiMAX, DVB-S2 etc. It is presented by researchers who have extensive experience in this area, both with a background in theory and practical methods of receiver implementation. During the course attendees will obtain “hands-on” experience in selected areas through MATLAB-based tutorials.

Assumed knowledge: Basic digital signal processing and digital communication systems, Matlab programming.

Presenters

Bill Cowley worked initially for the Post Master General’s Department, then joined DSTO in 1979. In 1985 he completed his Ph.D. with Adelaide University and then he moved to the Digital Communications Group at the South Australian Institute of Technology. During the last 20 years Bill Cowley has worked mainly in modem signal processing.  This has included a wide range of bit rates, access methods and application areas. He is currently Professor of Communications Signal Processing and Leader of the Applied Signal Processing Research Group in ITR at the University of South Australia.

Mark Reed pioneered the area of iterative receiver design with the publication of his PhD thesis titled "Iterative Receiver Techniques for Coded Multiple Access Communication Systems" in 1998. He has worked in industry and research positions for the last 15 years with positions in the U.S.A., Switzerland, and Australia. His experience includes working in a team that designed and developed a world first Satellite-UMTS Modem and research into advanced signal processing schemes, including MUD, for link improvement in UMTS. Since April 2003 Dr Reed is employed as a Senior Researcher at NICTA and is also an Adjunct Fellow at ANU where he is involved in research, education, commercialisation, and linkages in the wireless signal processing program. He has over 45 international journal and conference papers and has been listed as inventor on six patent applications.
