| Abstract: | A novel beamformer is proposed, based on the Duvall beamforming structure. The Duvall beamformer, which blocks the desired signal by using its direction information, suffers from performance degradation due to errors in the information. The proposed beamformer is very insensitive to such errors by employing a simple direction estimation, which is well suited to the Duvall structure. |
