Wiener滤波器在小波变换域的应用

Application of Wiener Filter In Wavelet Domain

对于任意信号,在MSE意义上最优的信号估计是Wiener滤波器。小波变换在时域和频域上同时具有局部化特征,在信号处理中得到了广泛应用。论证了小波域上Wiener滤波器的设计,提出了应用的方法。

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.
