dc.description.abstractThis work proposes an adaptive beamformer based on generalized sidelobe canceller (GSC) structure with novel blocking matrix design. The classical GSC presented by Griffiths and Jim suffers from desired signal cancellation problems due to the complicated acoustic environment. This work utilizes the pseudo-inverse property of matched filters and subarray structure to design a new blocking matrix of the GSC. For practical implementation, matched filter ratios between microphone pairs are estimated, instead of estimating matched filters from the sound source to each microphone. Simulation results are presented to show the effectiveness of the proposed method.en_US
