Scheduling of energy harvesting for multi-antenna wireless powered communication networks (WPCNs)

, 2020
Hybrid beamforming has been introduced as a low-cost alternative to digital beamforming with its capability to operate with fewer RF chains than the number of antennas. However, the diminishing degree of freedom from utilizing fewer RF chains results in considerable performance degradation.
