Fig. 4From: Multichannel speaker interference reduction using frequency domain adaptive filteringMWF approach for speaker m=1. The box denotes the buffering of the previous K − R samples. With the aid of a PSD estimation, a Wiener filter W1(ℓ,k) is adapted to reduce the interferer signals in microphone channel y1(n). As indicated by the three layers, microphone channels y2(n) and y3(n) are enhanced by changing the input signals accordinglyBack to article page
