小波变换处理带噪语音信号，对于低信噪比的情况下相当有效，直接改文件名就可完成-Wavelet Transform of Noisy Speech signal processing for low SNR case quite effectively, direct to the file name can be completed

for using this code need to use signal toolbox and general toolbox in your matlab Using Daubechies transform to compress the image (showing remaining coefficen of Thresholded Image) and then using Inverse 2D Daubechies transform and finding t

对语音信号进行小波变换，达到将低信噪比的要求。(Wavelet transform is used to achieve low SNR requirements)

ecg信号处理，基线漂移，小波变换、snr mse(ECG signal processing, baseline drift, wavelet transform, SNR MSE)
