LCMVベースのScan-and-Sum Beamformerによる面領域内音源の抽出

抄録

This paper addresses the extraction of the in-region sound sources. To solve this problem, we propose an LCMV-based Scan-and-Sum Beamformer (LCMV-SS-BF) that can extract sources within a specified wide and continuous region by integrating an LCMV Beamformer (LCMV-BF) for continuous region separation and a Scan-and-Sum Beamformer (SS-BF) for wide-area source separation. Numerical simulations using convolutional source datasets showed the effectiveness of source extraction by LCMV-SS-BF.
