| Abstract: | In this paper, the theory of wavelet thresholding denoising is discussed. The different wavelet estimators are presented , including all kinds of threshold functions and threshold values. ECG signals are given as an example to validate the denoising technology's good effects. In the end , the future tend of wavelet denoising is pointed out. |
