| Abstract: | This paper deeply analyses and researches the method of signal denoising based on wavelet transform. Combining with the denoising principle,the rational selection issue concerning more suitable wavelet base and the best threshold rule in actual application is discussed and compared.Experiment results indicates that the use of this denoising method can achieve the denoising of signals of various kinds,with obvious effects obtained. |
