Two-channel adaptive microphone array with target tracking

摘要

This paper propose a new robust adaptive micro- phone array suibable for a two-channel audio input system. This microphone array tracks a target speaker by using two Adaptive beamformers and can reduce the target signal Distortion, which is caused when the target signal is can- Celed in the case where the target direction differs from the Initial look-direction of the microphone array. To enable Target tracking, the directional responses of the beamform- Ers are exploited estimate the directions of arrival(DOA) Of the target and the interference.
