说明：  MATLAB软件对不同发射天线、不同接收天线、不同信噪比下的MIMO系统容量进行仿真，得出在不增加带宽和天线发送功率的情况下利用MIMO信道成倍地提高无线信道容量
(MATLAB software for different antennas, different antenna, different SNR of the MIMO system capacity for simulation, obtained without increasing the bandwidth and the antenna transmit power where the use of MIMO channels to improve wireless channel capacity multiplied)
