This paper introduces the basic principle of lifting method, gives the steps and methods of lifting wavelet, and expatiates the fast algorithm of lifting wavelet transform, discusses how to use lifting wavelet transform to denoise the actual signal, compares the traditional wavelet to Noise and enhance the effect of the wavelet denoising. The simulation results show that the lifting wavelet algorithm can be better applied to signal denoising, simple and has a good denoising effect.
