三个空间错开漩涡光束左旋螺旋形焦点在YZ平面的强度分布计算程序(YZ distribution of left handed spiral focal spot)

MATLAB采用LMS,MMSE,RLS,SINR,SMI算法实现波束形成(MATLAB uses LMS, MMSE, RLS, SINR and SMI algorithm to realize beamforming.)

程序仿真了瑞利信道，分析和大量实测表明，多径效应使接收信号包络变化接近瑞利分布。在典型移动通信中，衰落深度达30dB左右，衰落速率约30~40次/秒。(Rayleigh channel simulation procedures, analysis and extensive test shows that the received signal multipath effect changes in the envelope close to the Rayleigh distribution. In a typical mobile communication, fading depth of about 30dB, the decline rate of about 30 to 40 times/sec.)

这个程序得到的lambda_1不能当做最大lyapunov指数，因根据所作出的曲线选择线性区进行拟合，此处的处理是为了程序的方便 (This program was not as maximum lyapunov lambda_1 index, based on curve fitting due to the linear region selection made, in order to deal with here is a program of convenience " )

WINNERⅡ信道代码的主程序，主要是参考历程进行系统的配置，给出WINNERⅡ信道调用的参考例程(WINNER ii main channel code, mainly with reference to the history of the system configuration, the channel is given WINNERⅡ reference routine calling)
