小波降噪程序，可对信号进行heursure阈值消噪处理。,Wavelet Denoising procedures can signal heursure threshold de-noising processing.

方波信号削噪，用sym8小波进行三层分解并用heursure软阈值进行小波系数阈值化-Cut a square wave signal noise, three with sym8 wavelet decomposition and use heursure soft threshold wavelet coefficients thresholding

针对提出的故障信号，利用awgn加噪，对其进行小波软硬阈值降噪，提出一种改进阈值，利用五种自适应阈值函数sqtwolog、rigrsure、heursure、minimaxi和ddencmp中阈值选取原则，对软阈值、硬阈值和改进阈值进行降噪效果对比。(In view of the proposed fault signal, the wavelet soft and hard threshold de-noising is carried out by AWGN adding noise, an
