Wavelet transform has great application potential in the field of signal processing. In the discontinuous neighborhood of the signal, the threshold method denoising will cause the pseudo Gibbs phenomenon. This paper introduces the wavelet threshold de-noising method with translation invariant wavelet threshold denoising method followed as the improved algorithm, and respectively uses these two denoising methods to process the synthetic signal, so as to prove the effectiveness of the translation invariant wavelet threshold denoising method.
