“…This verifies the accuracy of the derivations of both PDFs for NL-EH models. Please note that for all cases, the area of shaded regions is always equals to one which verifies the PDF calculations given in (10) and (13). Also, note that both histograms are bounded to the given boundaries defined in (10) and (13).…”

“…Linear, piece-wise linear, and nonlinear EH (NL-EH) models characterize the amount of harvested power [1,[4][5][6][7][8]. Most works in the literature consider the linear EH model which has a direct proportion between the input and output powers of the EH circuit [1,9,10]. On the other hand, the piece-wise linear EH model is considered in the literature [4,5] which provides the same amount of energy as in the linear model for the small amount of input power.…”

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 [12] the TSR protocol was applied to the AF and DF relay protocols and an evaluation of the throughput efficiency was carried out. The performance of SWIPT on a cooperative communication system by implementation of the Partial Relay Selection scheme on Decode-and-Forward (DF) relay protocol is reported in the paper [13]. In [13] two SWIPT schemes are applied, static power splitting based relaying (SPSR) and optimal dynamic power splitting based relaying (ODPSR), and system performance is displayed in outage probability values with parameters of SNR value, number of relays and harvesting efficiency value.…”

This study examines the system’s performance with implementation of the energy harvesting (EH) techniques at source node, S and relay node, R. The RF signals which are used to energy harvesting proccess are broadcasted by destination node, D. The information signals from S are sent to D via a R in a cooperative communication framework. The R uses the amplify and forward (AF) protocol to forward the received signal from S to D. We propose a network system which contain of three femto cells, and an access point of each femto cells work as a relay (R), in a macro cell with a base station or eNB as a destination (D). To find the best R for forwarding the information signal from S to D, we choose the partial relai selection strategy. From the simulation results can be shown that the throughput system and the outage probability system are affected by the location of S or the distance of between S-R and S-D. Also affected by the access point power of femto cell that is connected to electric source, and time swithing factor, ρ which is used to harvest energy at S and R nodes. The shorter distance of between S-R and S-D results a better value of throughput system and the outage probability system, since the gain channel value will be high and increases the SNR value at D. More bigger the power from battery of access point femto cell that is used together with the harvested power by R to forward the signal will result a better value of throughput system and the outage probability system. More smaller time swithing factor, ρ results more time period for transmitting signal by S and forwarding sinyal by R, therefore increases the transmit power at S and R. Increasing the transmit powers result the increasin SNR value at D, and result a better value of throughput system and the outage probability system.

SummaryWe study the energy harvesting (EH)‐assisted system model based on the performance of a dual‐hop cooperative communication system that is subjected to Nakagami‐ fading. Through the partial relay selection method, the selection of th best relay (BR) is performed among amplify and forward (AF) relays, which can harvest energy from radio frequency signals. At the receiver, the selection combining scheme is considered to select between the signals of th best relaying path and the direct path. For this considered system, we compute the closed‐form expressions of outage probability (OP) and the average symbol error rate (ASER) for higher order quadrature amplitude modulation (QAM) techniques, especially for rectangular QAM, cross QAM, and hexagonal QAM. Further, a new moment‐generating function expression is obtained which is used to derive the ASER expression related to the generalized non‐coherent modulation technique. We also give the asymptotic expression of OP to find out the diversity order. Furthermore, we study the effect of fading parameters, th BR, and other factors on system behavior. Finally, we verify the derived expressions with Monte Carlo simulations.
