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
