Wavelet decomposition and reconstruction denoising based on the mallat algorithm

ZHONG Li-hui1,WEI Guan-jun2(1.Southwest Forestry University,Kunming 650224,China;2.Zhengzhou University,Zhengzhou 450001,China)  
In order to extract the ECG,the wavelet decomposition and reconstruction denoising based on the Mallat algorithm was discussed in the application of ECG denoising.Firstly,determined the wavelet base function;secondly,determined the decomposition layers;thirdly,re-constructed the ECG by the useful signals;finally,simulation experiments showed that the wavelet decomposition and re-construction denoising can effectively filter out the baseline drift and high frequency of the EMG interference.
