New Beamformer for Coherent Signal Reception in the Presence of Uncorrelated Interferences
In this paper, a new beamformer is proposed for coherent signal reception with the assumption that the directions-of-arrival (DOAs) of the uncorrelated interferers are available. Here, the composite vector of the coherent sources is first estimated based on the use of a transformation matrix to eliminate the uncorrelated interferers. Then the optimum beamforming is performed based on the estimated composite vector and the eigenstructure of the array correlation matrix. Experimental results show that the proposed beamformer achieves the optimum performance and rapidly converges.
