Efficient Channel Feedback Scheme for Multi-User MIMO Hybrid Beamforming Systems

Efficient Channel Feedback Scheme for Multi-User MIMO Hybrid Beamforming Systems

This paper proposes an efficient channel information feedback scheme to reduce the feedback overhead of multi-user multiple-input multiple-output (MU-MIMO) hybrid beamforming systems. As massive machine type communication (mMTC) was considered in the deployments of 5G, a transmitter of the hybrid be...
