The paper introduces wavelet transformation and the basic theory and method of signal denoising based on wavelet transformation.Wavelet transform technology is adopted for threshold processing of noise and removing noise in the unsteady signals.And the computer simulation of signal denoising based on wavelet is done using Matlab.The results indicates that the effect of signal denoising based on wavelet transform is better than that of signal denosing based on the Fourier transform.
