中文说明：用于信号特征提取、信号消噪，包含特征值与特征向量的提取、训练样本以及最后的识别，基于互功率谱的时延估计，仿真效果非常好，主要是基于mtlab的程序，基于分段非线性权重值的Pso算法。
English Description：
For signal feature extraction, signal denoising, contain eigenvalues and eigenvector extraction, training samples and the final recognition, based on the cross power spectrum time delay estimation. The simulation effect is very good, mainly based on MTLAB procedures, based on the piecewise nonlinear weights of PSO algorithm.
