Self-Interference-Aware AS-Assisted Tri-Hybrid Beamforming for Full-Duplex Massive MIMO
Yuanzhe Gong, Cheng-Jie Zhao, Tho Le-Ngoc
This paper proposes a tri-hybrid beamforming (tri-HBF) scheme with antenna-selection (AS)-based reconfigurable sub-arrays for full-duplex (FD) massive multiple-input multiple-output (mMIMO) systems. A sub-connected HBF architecture is adopted, where AS is performed in a group-wis…
