说明：  mimo的注水原理算法源代码，天线数为4*3，算法原理是空时无线通信导论上的算法，经过调试，完全可以运行，对学习mimo注水原理算法的同学很有帮助。
(The principle of algorithm for mimo water source, the antenna number is 4* 3, the algorithm principle is introduction to the space-time wireless communications algorithms, after commissioning, can run on the principle of learning algorithm for mimo water helps the students.)
