Matlab
信号去噪的基本步骤：
（1）信号的小波分解；
（2）小波分解高频系数的阈值量化；
（3）信号的小波重构。使用分解的低频系数以及阈值量化后的高频系数进行小波重构。
(The basic steps of signal denoising:( 1) of the wavelet decomposition of signals ( 2) the high frequency coefficients of wavelet decomposition threshold quantization ( 3) the signal wavelet reconstruction. Using the decomposition of the low frequency coefficient and threshold quantization the high-frequency coefficient after wavelet reconstruction.)
