| Abstract: | A robust Capon beamformer (RCB) with a new constraint on the uncertainty of nominal array steering vector (ASV) is proposed in this paper. The new constraint is constructed by replacing the nominal ASV with a projected one onto the signal-plus-interference subspace. The proposed RCB achieves higher output signal-to-noise-plus-interference ratio (SINR) compared with the conventional RCBs. Theoretical analysis and simulation results show the effectiveness of the proposed method. | ||
