Optimal Power Splitting of Full Duplex Wireless Powered Communication Networks with Two-Way Relay

Abstract

In this paper, we consider a two-way full-duplex wireless power communication network. Two source nodes and the relay node operate in full-duplex mode, considering the self-interference at three nodes in this paper. On the basis of it, we analyzed how to distribute power to maximize system throughput of the two-way full-duplex wireless power communication network. The two source nodes with energy limitation are powered by the relay node, and then transmit information of full-duplex mode. The process is divided into two time slots, the first time slot, two source nodes with two directional antennas utilize the relay node to energy harvesting. In the second time slot, the two source nodes use the harvested energy to transmit their own information to the relay node and relay node amplify and forward this one. To maximize throughput, we investigated how to perform optimal power allocation in terms of the full-duplex relays with two-way perform.
