Abstract

In this paper, we present a receiver for maximum signal-to-interference plus noise ratio (SINR) for MIMO channel in DS/CDMA communications systems in frequency-selective fading environments. The proposed system utilizes full degree of freedom in FIR filters at both the transmitter and receiver antenna array. We develope at our system by attempting to find the optimal solution to a general MIMO antenna system. Also we derive a single user joint optimum scenario and a multiuser SINR enhancement scenario and prove that the existing algorithm is a special case of our method. In addition, we propose a system which uses zero correlation duration spreading sequence, with which superior performance is guaranteed over the existing algorithm. Extensive numerical results reveal that significant system performance and capacity improvement over conventional approaches are possible.
