| Abstract: | The door method to de-noise on the basis of wavelet transform is emphatically analyzed in this paper. As well as the rule and arithmetic of wavelet transform door value choice. Through computer emula- tion, the performance of various rules is compared and the filter effect on the basis of wavelet transform door method to de-noise is also validated. According to emulation result, this kind of method can restrain broadband noise effectively by using this de-noising technique. |
