A precedence effect based far-field DoA estimation algorithm
Wen-Sheng Chou, Tai-Shih Chi · 2013
A robust far-field DoA estimation algorithm is proposed in this paper. The algorithm is inspired by the precedence effect which results in humans robust capability in localizing sound sources. The algorithm implements the concept of the precedence effect by applying a proper threshold and an onset detection mechanism in the cross-correlation domain. Experiment results show that by cascading the proposed algorithm to a conventional cross-correlation based DoA algorithm, the accuracy of the DoA estimation is significantly improved in far-field test conditions.
