| Abstract: | The Wiener filter is optimal for any signal in the sense of MSE.The wavelet transform possesses the localizing character at the same time in the time domain and frequency domain,so it is widely used to signal processing.The design of Wiener filter in wavelet transform domain is demonstrated and some methods of application are bring forwarded. |
