摘要：

This paper introduces the computing method of channel capacity in MIMO Wireless Channel. It mainly analyzes and compares the ergodic capacity of independent and identically distributed (iid) multiple-input multiple-output (MIMO) [1] Rayleigh flat fading channels when channel state information (CSI) is unknown and known to the transmitter but perfectly known at the receiver Moreover a computer simulation with Matlab is implemented. The simulation result indicate that the performance of channel capacity with the optimal power allocation outperform the average power allocation. And, it also shows that. the capacity is asymptotically linear in the logarithm of SNR and the minimum of the number of transmit and receive antennas with the growth of SNR
