不同的信噪比会产生不同的误码性能，本程序通过不同信噪比的设置，比较了系统的性能，能实现八个性能对比的图像-Different signal to noise ratio will produce different error performance of this program through a different signal to noise ratio set to compare the performance of the system to achieve the eight

MIMO系统的仿真，实现不同M值误码率与与信噪比的关系图像。-Simulation of MIMO system, the realization of different M value image relation between error rate and snr.
