Under the assumption that the channel state information was available only at the receiver,the capacity of MIMO systems in Rayleigh fading channel was investigated on the basis of information theory. Three special expressions for the MIMO capacity over ergodic flat fading channel were derived.An asymptotic formula for MIMO systems with equal number of transmit and receive antennas in small SNR was also given. Simulation results show that this approximation is relatively accurate.

以信息论的观点为基础,在假设信道状态信息仅收端已知的情况下,采用等功率发射方案,研究了瑞利衰落信道下MIMO系统各态历经信道容量,推导了三种特殊MIMO信道的各态历经信道容量表达式,以及在小信噪比下等收发天线MIMO系统的容量近似公式,并通过仿真进行了验证,仿真结果表明该近似公式比较精确。
