Robust Adaptive Beamforming Method Based on Steering Vector Phase Correction and Covariance Matrix Reconstruction

Steering vector (SV) mismatch caused by the DOA uncertainty in the source leads to a remarkable performance degradation for adaptive beamforming particularly in situation where the training data ...

Phase Shift Matrix Design With Vector Quantization in RIS-Aided Physical Layer Key Generation

Abstract: The key generation rate (KGR) of physical layer key generation (PLKG) is severely restricted in quasi-static environments due to a lack of entropy. To address the problem, a reconfigurable ...
