Hybrid BF Structures

Hybrid BF Structures

In this article, optimal designs of hybrid beamforming structures are investigated, with the focus on an (the number of transceivers) by (the number of active antennas per transceiver) hybrid beamforming structure.

Optimal analog and digital beamforming designs in a multi-user beamforming scenario are discussed. Also, the energy efficiency and spectrum efficiency of the × M beamforming structure are analyzed, including;

  • their relationship at the green point (i.e., the point with the highest energy efficiency) on the energy efficiency-spectrum efficiency curve,
  • the impact of on the energy efficiency performance at a given spectrum efficiency value
  • the impact of on the green point energy efficiency
