“…is the Meijer-G function ( [35], 9.301). Finally, the throughputs of linear and piecewise linear EH models are obtained by substituting (48) and ( 50), respectively, into (26). Different from the NL-EH models previously given in the literature, we obtained closed-form outage probability expressions for the Nakagami-m channels in equations ( 32) and ( 42) and for the special case of Rayleigh fading channels in equations ( 37) and (45) for NL-EH-1 and NL-EH-2 models, respectively.…”

“…Theoretical curves for average harvested power are obtained from ( 14), (20), (21), and (22). Theoretical throughput curves are depicted by replacing (32), (42), (48), and (50) into (26). For the BER analysis, theoretical results are obtained by applying (54), (69), and (74).…”

“…The performance is provided for different system parameters, and generally, the PS EH mode outperforms the TS EH mode. System performance of the WPC DH AF relaying system is investigated in [26] where both S and R are power-constraint nodes and harvest their power from a dedicated PB. BER of the system is obtained for different parameters, and theoretical derivations are derived considering the linear EH model.…”

As a massive number of nodes are expected to be connected to each other in next-generation wireless networks, the power supply of such multiple-antenna nodes is a challenge and requires new and sustainable solutions. Radio frequency energy harvesting (EH) is among the promising approaches to solve this issue. In this paper, two new mathematically tractable nonlinear EH (NL-EH) models are proposed, for which the system performance is evaluated in terms of average harvested power, throughput, and bit error probability. The system consists of one multiantenna power-constraint source harvesting its power from a dedicated power beacon and transmitting its signal to a destination equipped with multiple antennas. For a comprehensive analysis of the system, closed-form expressions are derived for Nakagami- m fading channels and the special case of Rayleigh channels. For comparison purposes, the performance derivations in Nakagami- m fading channels are provided for linear and piece-wise linear EH models given in the literature. Besides, the simulation results are obtained by applying the Monte-Carlo method for NL-EH models existing in the literature. The results provide a broadening view of EH systems and thoroughly compare the proposed NL-EH models with linear, piece-wise linear, and NL-EH models available in the literature. Hence, these provide better insights towards the analyses and design of EH systems.

“…In the information‐theoretic approach expressions for the outage probability, capacity, and/or throughput are analysed. The works in [3–9] are among the few which provide communication‐theoretic analysis to deduce average bit error rate/average symbol error rate (SER). The communication‐theoretic approach provides more realistic results as it involves information on modulation and demodulation techniques.…”

This paper investigates the performance of a two-hop decode-and-forward relaying system when the source node is energy-constrained and it harnesses energy using the radio frequency signal radiated by the relay node. Data transmission at the energy-constrained source node is enabled by the energy harvested at the node. The analysis is presented for two modulation schemes: coherent M -ary phase-shift keying and orthogonal non-coherent M -ary frequency-shift keying. Analytical and asymptotic expressions for the average symbol error rate are derived for the considered modulation schemes under − shadowed fading. The results are plotted to investigate the system's performance with variation in modulation order, fading parameters, and relay location.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.
