说明：  MIMO系统容量仿真程序分为两个。其中 文件夹1为：发射天线数为4，接收天线数逐渐增大时MIMO系统容量的仿真程序。 文件夹2为：接收天线数为4，发射天线数逐渐增大时MIMO系统容量的仿真程序。
(MIMO system capacity simulation program is divided into two. One folder 1 as follows: the number of transmitting antennas is 4, gradually increasing the number of receive antenna MIMO system capacity when the simulation program. Folder 2 as follows: the number of receiving antennas 4, gradually increasing the number of transmission antennas, MIMO system capacity when the simulation program.)
