Abstract:

In order to improve the beamformer's robustness against DOA estimation error, reduce the beamformer's attenuation against the target signal, this paper proposes an improved beamformer algorithm based on the frequency focusing, which makes the beam's pattern in the sound bandwidth tend to be uniform, reduces the speech distortion, and further improves the effect of the speech enhancement.
