| Abstract: | The filtering method used in this paper is based on wavelet transform, which first simply ill- ters out the high frequency noise, then the noise in the similar frequency band with the useful signal by setting soft threshold. This method leads to good filtering result and proves to be inefficient through real time digital simulation system. |
