Capacity of multiple antenna systems in Rayleigh Fabing channels

摘要

The asymptotic capacity of a communication system with m transmit and n receive antennas is derived for the case where the channel is known at the receiver only. Then, the general expression of the capacity when the channel is also known to the transmitter is presented. The asymptotic capacity is also given for this case. Finally, the optimal processing at the transmitter required to achieve that capacity is determined.
