| Abstract: | A multichannel wideband signal dereverberation and enhancement method is proposed in this paper. It uses the blindly estimated impulse responses (IRs) relating the signal source and each sensor to form a multiple input inverse filter (MINF) for speech dereverberation and ehancement with extended generalized sidelobe canceller (GSC). With the replacement of MINF for fixed beamformer and modification of blocking matrix in conventional GSC, the resulting extended GSC not only dereverberate the distorted target signal, but also suppress the interference/noise. Computer simulation results show the effectiveness of the proposed method. | ||
