  Using wavelet method to remove noise is an important aspect of wavelet analysis engineering practice. This paper briefly introduces wavelet decomposition and reconstruction, wavelet denoising principle, hard threshold method, soft threshold method, and translation invariant method. And Matlab is used to simulate several typical signals superimposed with Gaussian white noise.
