The Generalized Multichannel Wiener Filter

Abstract

In the past few years, research on speech enhancement using acoustic sensor networks consisting of spatially distributed microphones has gained significant interest [28, 29, 30, 31, 7, 32, 6, 33, 34, 35, 36, 37]. Compared with a microphone array at a single position, spatially distributed microphones are able to acquire more information about the sound field. The usage of spatially distributed microphones allows to employ combining techniques for speech quality improvement in reverberant and noisy conditions.
