Hankel Meets NOMP: Matrix Pencil and Newtonized Orthogonal Matching Pursuit for Robust Beamforming via Interference-Plus-Noise Covariance Matrix Reconstruction
Beamforming based on interference-plus-noise covariance matrix (INCM) reconstruction is a cornerstone of robust adaptive beamforming. Conventional Capon type and maximum entropy type methods typically require numerical integration, leading to stability issues and integration errors. Sparse recovery-based approaches, wh...
