The method of signal denoising based on wavelet thresholding is proposed in this paper. At first, it introduced principle of wavelet multiresoludion analysis. Secondly, three methods of selecting threshold are described. Then, the method of choosing threshold was introduced. At last, according to the computer simulation results, the performance of signal denoising based on wavelet thresholding were shown and the best method of choosing threshold has been found.

Keywords:Multiresolution analysis. Signal denoising. Wavelet threshold
