摘要：

A method for estimating direction of arrival (DOA) of multiple speech signals based on a histogram mapping (HM) method is proposed. The HM method is applied to the triangular microphone array with three microphones located at the vertices of an equilateral triangle with a known inter microphone distance. A plane wave traveling from the direction angle is considered and a time difference of arrival (TDA) vector consisting of the TDAs of the three microphone pairs is defined. One speaker is set at 0°, and the direction of the other speaker is varied from 10° to 180° at 10° intervals. The directions of two speakers are correctly determined when their directions are 120° apart, and the beamforming method gives estimation results with a significant amount of bias and deviation errors.
