Abstract :
Up to now most research on the capacity of MIMO systems has been carried out on a point-to-point link. However the capacity and BER performance of such systems in a cellular environment have not been much investigated. In this paper, we investigate the BER performance of a space-time block coded MIMO system in the presence of an interferer, which is treated as unknown, and interferers in a cellular system. The concept of a spatially pre-whitened matched filter is used to improve the BER performance of the system in which interference will not in general be spatially white.
