Abstract

Abstract

In the process of the beamforming for the coherent signals, because of the estimation error of the coherent signal energy and the estimation error of covariance matrix R, and perturbation error on the steering vector, the output SINR of beamformer drops badly. In this paper a new beamformer is presented based on the LS shaping from quantum signal processing. As a robust beamformer it shows the good performance in the circumstance discussed above. Analysis and simulations are given to prove the efficiency and validity of the new beamformer.
