Abstract
In order to avoid the desired signal cancellation, a new robust adaptive beamformer based on matrix projection method is developed. The proposed method mainly adopts spatial division method and Capon beamformer. The computation complexity of the proposed beamformer is in the same order as the complexity of Capon beamformer. Moreover, there is no iteration for the optimum solution in the proposed algorithm, which is more efficient in computation. Theoretical analysis and simulation results demonstrate that the proposed beamformer can effectively suppress the information of the desired signal.
