说明：  小波变换去噪算法，可以自己改变阈值函数与分解层数(Wavelet transform denoising algorithm can change the threshold function and decomposition level by itself)

对于一个随机的非高斯信号或者一个确定信号有很多的信息（远不止功率谱...）。本工具用来分析高阶谱和时频分布。(For a random signal or a set of non-Gaussian signals have a lot of information (far more than the power spectrum ...)。 This tool is used to analyze higher-order spectra and time-frequency distribution.)
