DOA Estimation of Speech Signal Using Microphones Located at Vertices of Equilateral Triangle


In this paper, we propose a DOA (Direction Of Arrival) estimation method of speech signal using three microphones. The angular resolution of the method is almost uniform with respect to DOA. Our previous DOA estimation method [1] using the frequency-domain array data for a pair of microphones achieves high precision estimation. However, its resolution… (More)
