An Adaptive Beamforming Method Based on Post-Multistage Wiener Filter For the Speech Enhancement
In the speech communication systems such as car, video conference and multimedia conference, the speech signal received by a microphone is often interfered by environment noise which degrades the quality of the signaL In order to suppress the coherent and incoherent noise signal more effectively, an adaptive beamforming method based on post multistage Wiener filter is proposed in this paper. It make use of the advantage of the multistage Wiener filter and gener alized sidelobe canceller (GSC). The simulation results show that it has better de-noise effect than the conventional microphone array speech enhancement.
