| Abstract: | The basic method of wavelet threshold denoising based on the principle of the multiresolution analysis is presented,and several thresholdings and threshold selection rules are also presented.Plenty of background noise is filterated by the wavelet threshold denoising with local feature well in time?frequency domain.It's shown by the perfect result of simulation experiment that the method of wavelet threshold denoising is very suitable for signal denoising. |
