Abstract

We analyze the capacity region for the multiple access channel with multiple transmit and receive antennas. For Rayleigh fading with perfect channel state information at the receiver (CSIR) and only a knowledge of the spatial correlations at the transmitter, we determine the optimal transmit strategies to achieve the points on the boundary of the capacity region under various correlation models
