信号处理中的旋转不变子空间法，最终的权值矩阵就是滤波器的系数，使用拉亚普诺夫指数的公式，借鉴了主成分分析算法（PCA），使用高阶累积量对MPSK信号进行调制识别，本程序的性能已经超过其他算法，基于chebyshev的水声信号分析，有小波分析的盲信号处理。- Signal Processing ESPRIT method, The final weight matrix is ??the filter coefficient, Raya Punuo Fu index using the formula, It draws on principal component analysis algorithm (PCA), Using high-order cumulants of MPSK signal modulation recognition, This program has exceeded the performance of other algorithms, Based chebyshev underwater acoustic signal analysis, There Wavelet Analysis Blind Signal Processing.
