中文说明： 用于信号特征提取、信号消噪，包括广义互相关函数GCC时延估计，实现串口的数据采集，基于欧几里得距离的聚类分析，可以得到很精确的幅值、频率、相位估计，基于分段非线性权重值的Pso算法。
English Description：
Used for signal feature extraction, signal denoising, including generalized cross correlation GCC function for time delay estimation, to realize the serial port data acquisition, Euclidean distance based clustering analysis can get very accurate amplitude, frequency and phase estimation, based on piecewise nonlinear weight value of the PSO algorithm.
