Signal Filtering Based on Wavelet Transform
Jing Shuang · Journal of China University of Mining and Technology · 2000
Signal filtering based on wavelet decomposition and reconstruction was presented． Firstly， the signal was decomposed Into different channels by wavelet transform． Then the signals of some channels were deleted and the signals of other channels were reconstructed， so the noise in the original signal was filtered．example of signal filtering using wavelet packet an was provided． The result demonstrates that the new method has excellent features in signal filtering and weak signal extracting．
