Minimum Variance Beamforming Based on Covariance Matrix Reconstruction Using Orthogonal Vectors by Saman Rezaeizadeh, Mehdi Bekrani

“…In this paper, in order to make the beamformer robust to the incorrect estimation of the data covariance matrix, a covariance matrix reconstruction method using the orthogonal steer vectors obtained by the Gram Schmidt algorithm along with a diagonal loading is employed. Simulation results show the superiority of the proposed method in the improvement of beam pattern, angle estimation of interferences, and output SINR level, compared to the counterparts.…”
