Abstract
A broadband beamforming method based on wavelet filterbanks and adaptive beamforming is proposed for speech enhancement in this paper. First, using the wavelet analysis filterbanks, noisy speech signals are transformed into wavelet domain with wavelet coefficients as output. Then the beamforming based on generalized sidelobe canceller (GSC) operates on the wavelet coefficients. Finally, the enhanced full-band speech signals were finally reconstructed by synthesizing the enhanced subband speech signals by used of the wavelet synthesis filterbanks. Simulation results demonstrate its effect.
