Abstract
In this paper, we discuss a unified approach and its simple algorithm for estimating and tracking the location of the desired talker in the far field and the near field by microphone arrays. The approach is uni fied for the far field and the near field and can enhance the effectiv e power of the talker's signal. The simple algorithm further avoids si ngular-value decomposition (SVD) computations and is suitable for real -time processing. Computer simulations and experiments using actual ar ray data support the techniques.
