Beamforming techniques are becoming popular in a wide spectrum of applications thanks to their promising performance. We consider applying the minimum variance distortionless response (MVDR) beamformer in a dynamic scenario, where the desired speaker, the noise components or microphone array may move. The generalized sidelobe canceler (GSC) structure offers a convenient implementation of the MVDR,...
The problem of speech enhancement using a distributed microphones array in a dynamic scenario where speaker, noise and microphone arrays are free to move is considered. The transfer function generalized sidelobe canceler (TF-GSC) spatial filter [1] which optimizes the minimum variance distortionless response (MVDR) criterion is used for enhancing the desired speech signal. A novel speech presence...
Global availability of wide unlicensed spectrum and advances in CMOS technology enable high value use cases in 60 GHz. Coexistence and interoperability between application types is crucial for 60 G ecosystem success.
