说明：  该算法是经典的信噪比估计算法——最大似然估计算法，利用接收信道的先验概率密度函数，ML法能够很好的估计信号的信噪比(The algorithm is a classic signal to noise ratio estimation algorithm- maximum likelihood estimation algorithm, using the a priori receiver channel probability density function, ML method can be a very good signal to noise ratio is estimated)

说明：  基于matlab的衍射模拟，在毕业设计的时候顺便参考做的，有问题的话欢迎指出(Matlab simulation based on the diffraction, when the way in the graduate design reference do have problems, then welcome to point out)

说明：  kmeans函数：输入为类别数量k和数据矩阵A；输出为聚类结果A，和迭代次数，并将聚类结果数据以excel形式保存在工作路径下(k-means clustering algorithm error-free very practical)
