em算法的matlab实现，简单适合入门，可以参考(em algorithm matlab implementation, simple for entry, refer to)

利用GS算法优化傅里叶变换,经过上百甚至上千次的迭代，是的加密结果更加优化(GS for fourior transmisson)

本程序已被本人整理到WORD文档中，编程语言为MATLAB，本文设计的滤波器采用傅里叶级数展开法。模拟的杂波的功率谱密度采用BVURG法，概率密度函数的估计采用直方图估计法，设计参数皆在文档中表明。此程序已经验证是正确可执行的，并能生成图形，值得下载！(This program has been organized into WORD document I, the programming language MATLAB, the filter designed in this paper Fourier series expansion method. Simulated clutter power spectral density using BVURG method, the probability density function is estimated using histogram estimation methods, design parameters are indicated in the document. This procedure has been verified is correct executable, and can generate the graph, it is worth to download!)
