My research interest is space-time processing for broadband wireless access (BWA) systems. The introduction of antenna arrays at the base station and/or at the subscriber unit will enhance system performance, through-put and capacity. However, complexity is a major limiting factor in BWA systems and hence space-time algorithms with a good performance and complexity trade-off are sought. In summary my research investigates the introduction of space-time processing for BWA systems.
