Generalized Hybrid Beamforming for Vehicular Connectivity Using THz Massive MIMO

Hybrid beamforming (HBF) array structure has been extensively demonstrated as the practically feasible architecture for massive multiple-input multiple-output (MIMO). From the perspectives of spectral efficiency (SE), energy efficiency (EE), cost, and hardware complexity, HBF strikes a balanced performance tradeoff when compared with the fully analog and the fully digital implementations. Using the HBF architecture, it is possible to realize...
