Adaptive Microphone Arrays for Noise Suppression in the Frequency Domain
Klaus Uwe Simmer, Alexander Wasiljeff · 1992
Several methods for adaptive multichannel noise suppression of speech signals are compared. A modified weighting function is proposed to reduce linear distortions of the desired signal which may be introduced by the postprocessing system component. Experimental results using an array of four microphones placed at the corners of a PC monitor show a good agreement between theory and experiment.
