Abstract

In the pulse signals,random noise impacts seriously on feature extraction of the effective signal,denoising must be carried out.This paper analyzes the algorithm principles of the wavelet transform and wavelet packet.It uses them on the pulse wave to deal with denoising.The simulation result shows that the algorithm has the favorable characteristics and the better signal denoising effect compared with signal denoising algorithm based on wavelet transform.
