Throughput maximization for UAV-enabled wireless power transfer in relaying system

Simultaneous wireless information and power transfer (SWIPT) is an effective way for energy-constrained unmanned aerial vehicle (UAV) to prolong the network lifetime. In this paper, an amplify and forward (AF) relaying network is considered, where an energy-constrained UAV harvests energy and information simultaneously from base station and then transmits the information to the destination node. Based on time switching (TS) and power splitting...
