Robust Beamforming Against Direction-of-Arrival Mismatch Using Subspace-Constrained Diagonal Loading


In this study, a new subspace-constrained diagonal loading (SSC-DL) method is presented for robust beamforming against the issue of a mismatched direction of arrival (DoA), based on an extension to the well known diagonal loading (DL) technique. One important difference of the proposed SSC-DL from conventional DL is that it imposes an additional constraint… (More)
