中文说明：采用的是通用的平面波展开法,主要是基于mtlab的程序，最小均方误差（MMSE）的算法，算法优化非常好，几乎没有循环，外文资料里面的源代码，基于分段非线性权重值的Pso算法。
English Description：
Using the plane wave expansion method is common, is based mainly on mtlab programs, minimum mean square error (MMSE) algorithms, algorithm very well, almost no circulation, foreign materials inside the source code, based on Pso algorithms for nonlinear weighting value.
