中文说明：阵列信号处理的高分辨率估计，代码里有很完整的注释和解释，通过matlab代码，使用高阶累积量对MPSK信号进行调制识别，复化三点Gauss-lengend公式求pi，重要参数的提取。
English Description：
Array signal processing of high resolution estimation, code is very complete annotated and explained. By means of matlab code, using high order cumulants for modulation recognition of MPSK signals, complex three Gauss-lengend formula for PI, the important parameters of the extraction.
