[PDF][PDF] Fully Automatic Balance between Directivity Factor and White Noise Gain for Large-scale Microphone Arrays in Diffuse Noise Fields.
W Meng, C Zheng, X Li - INTERSPEECH, 2022 - isca-archive.org
In diffuse noise fields, a superdirective beamformer maximizes the directivity factor at the
expense of amplifying spatially white noise in low-frequency bands. It is extremely important …

On the Design and Implementation of Maximum SNR Beamformers for Scattered Speech Sources
Most existing microphone array beamforming methods for speech signal extraction assume
that speech sources obey the point source model. However, this assumption is not …
