SINR Maximizing Distributionally Robust Adaptive Beamforming

IEEE Transactions on Signal Processing
This paper addresses the robust adaptive beamforming (RAB) problem via the worst-case signal-to-interference-plus-noise ratio (SINR) maximization over distributional uncertainty sets for the random interference-plus-noise covariance (INC) matrix and desired signal steering vector.

Robust Adaptive Beamforming against Signal Steering Vector Mismatch and Jammer Motion

International Journal of Antennas and Propagation, 2015
Since adaptive beamformer suffers from output performance degradation in the presence of interference nonstationarity and signal steering vector mismatch, a novel robust null broadening adaptive beamforming is proposed. The proposed method is realized by

High Performance Robust Adaptive Beamforming in the Presence of Array Imperfections

International Journal of Antennas and Propagation, 2016
A high performance robust beamforming scheme is proposed to combat model mismatch. Our method lies in the novel construction of interference-plus-noise (IPN) covariance matrix. The IPN covariance matrix consists of two parts.
