Some blind beamformers require the direction of the desired signal. The performance of such type beam-formers can be severely degraded by a small directional error. We propose a blind beamforming scheme robust to directional error by employing a simple steering vector estimator. The performance of the proposed beamformer can be further improved by re-initializing the weights of the beamformer.
