Abstract :
In this paper, a new class of linear constraints is proposed with fewer derivatives for the previously-developed Generalized Side-lobe Canceller (GSC) algorithm. This improves noise cancellation of the beamformer in the presence of Direction-of-Arrival (DOA) mismatch compared to the adaptive beamformers with derivative constraints.
