TL;DR: Three relaying protocols for simultaneous wireless information and power transfer (SWIPT) in cooperative relay networks are presented and it is shown that, with the same SWIPT receiver, the IA-based system outperforms the EA- based system, whereas with the the same information receiving strategy, the PS protocol outper performs the TS protocol.

TL;DR: Simulation results show that system WSR and transmission time can be significantly enhanced by using energy beamforming and user cooperation and theoretically prove that the proposed methods guarantee the global optimum of both problems.

TL;DR: In this paper, a resource allocation problem is formulated to maximize the achievable information rate of a SWIPT-enabled two-hop OFDM decode-and-forward (DF) relay network, where a relay harvests energy from radio frequency signals transmitted by a source and then uses the harvested energy to assist information transmission from the source to its destination.

TL;DR: This paper investigates the simultaneous wireless information and power transfer (SWIPT) for two-hop orthogonal frequency division multiplexing (OFDM) decode-and-forward (DF) relay communication system, where a relay harvests energy from radio frequency signals transmitted by the source and then uses the harvested energy to assist the information transmission from the source to its destination.

TL;DR: A power splitting (PS)-based two-way relaying (PS-TWR) protocol is presented by employing the PS receiver architecture and an optimization problem under total power constraint is formulated to explore the system sum rate limit with data rate fairness.
