Hybrid Beamforming Design on Riemannian Manifolds for Wideband MIMO Systems

Hybrid Beamforming Design on Riemannian Manifolds for Wideband MIMO Systems

This paper proposes a novel, unified approach to design both radio frequency (RF) and baseband beamforming (BF) solutions for wideband hybrid multiple-input multiple-output (MIMO) systems using the Riemannian manifold optimization. The proposed two-stage optimization framework effectively addresses...
