Tracking direction of speaker for microphone array in the far field

摘要

This paper presents a method for tracking the direction-of-arrival (DOA) of a single speaker of interest in the far field for microphone arrays. The method can greatly enhance the effective power of the speaker based on a focusing transformation only for the speaker. The method is suitable for cases of low SNR or/and strong interfering signals. Computer simulations are given to support the proposed method.
