Abstract: In this paper, a special property of the fractional lower order covariance (FLOC)-based minimum variance distortionless response (MVDR) beamformer is found, which is the FLOC MVDR beamformer that has greater white noise array gain (WNAG)… read more here.

DOI: 10.1109/lsp.2022.3200581
Abstract: Traditionally, adaptive beamformers such as the minimum-variance distortionless response (MVDR) beamformer and generalized eigenvalue beamformer have been widely used for multi-channel speech enhancement with a single-channel postfilter. Recently, several approaches have been proposed to enhance… read more here.
