Noise reduction by using more reference signals in GSC beamformer

Nowadays, the use of microphone array (MA) technology has been popular, due to its high spatial diversity, high directivity factor and the steered beampattern towards the specified sound location. MA beamforming uses the spatial information about the direction of arrival of a helpful signal, the designed geometry of MA...
