Subband generalized sidelobe canceller - a constrained region approach
(2003) IEEE Applications of Signal Processing to Audio and Acoustics, 2003 p.41-44- Abstract
- The paper proposes an efficient microphone array processing technique for speech enhancement. The scheme incorporates the source and interference predefined regions into a subband generalized sidelobe canceller (GSC). The lower path consists of two space constrained beamformers to extract the interference information outside the source region. This information then serves as a reference for an improved adaptive noise canceller to enhance the target signal. The key feature of this approach is that it is voice activity detector free. Evaluations made in a hands-free situation show very good interference suppression with negligible expense on the source distortion.
