RESEARCH

My research interests are in the general areas of information theory and communication theory, with particular focus on wireless communication theory. Topics of interest to me within these fields include,

• Multi-user detection,
• CDMA and MIMO systems,
• Optimal transmitter, receiver and waveform (signature) design,
• Power control, medium access strategies,
• Multi-user information theory,
• User cooperation in wireless networks,
• Signal processing for communications,
• Quantization, source coding,
• Non-linear optimization, iterative algorithms.

NEW: A research assistantship position is available for a PhD student, starting February 2009. Details...
