| Abstract(in English) | We have proposed the speech noise reduction system based on the adaptive line enhancer (ALE) in frequency domain. The ALE has the de-correlation parameter between the input signal and the desired one and it make the noise in the input signal de-correlated with that in the desired signal. In this paper, we propose to insert the decorrelation parameter in each frequency domain signal and adjust it to an optimal value. The effectiveness of the decorrelation parameter in frequency domain is confirmed through computer simulations. |
