The Signal's Structure Method For Filter Of Wavelet

The wavelet analysis is developing on the foundation of Fourier analyze, conduct time- frequency analysis method, wavelet analysis ratio Fourier analysis have innate character advance, wavelet providing a kind of method for time domain and frequency domain of localized analysis at the same time, regardless analyzing signal of high frequency or low frequency rate, it can all automatically regulating time- frequency to orientation effective demand. In signal de-noising, speech signal take to generally not exceed 20 kHz, speech signal have got very complicated, it can be seen a not stabile signal. Compare to the de-noising method based on Fourier transformation, the de-noising method based on wavelet transformation already appear its advantage. Under the very...
