摘要：A novel adaptive beamforming technique with enhanced noise suppressioncapability. The technique incorporates the sound-source presence probability into an
adaptive blocking matrix. In one embodiment the sound-source presence probability isestimated based on the instantaneous direction of arrival of the input signals and voiceactivity detection. The technique guarantees robustness to steering vector errors withoutimposing ad hoc constraints on the adaptive filter coefficients. It can provide goodsuppression performance for both directional interference signals as well as isotropicambient noise.
