说明：  电池管理系统当中使用的一线通，节省成本 本人已测试成功 效果显著(Battery management system in the use of the first line, saving costs)

MIMO OFDM 预编码程序,可以用于MIMO系统的仿真(MIMO OFDM precoding system)

几个关于MIMO雷达的仿真程序，对学习相关内容的人有些帮助。(Several of the simulation program about MIMO radar to the study of relevant content people some help.)

for entropy H = entropy(S) this command will evaluate the entropy of S, S should be row matrix H = entropy([X Y Z]) this command will find the joint entropy for the 3 variables H = entropy([X,Y],[Z,W]) this will find H(X,Y/Z,W).. you can use it for any combination of joint entropies Please validate this function before using it
