“…Since in an equal transmit power case, the friendly jammers severely affect the system performance and do not provide a reliable information exchange process. 38,39 According to optimization results, the untrustworthy relay terminals are placed in the middle of the S 1 and S 2 terminals. The target rate, which is R, is set to 0.10 bps/Hz.…”

This paper investigates the leakage rate based untrustworthy relay selection strategies, which are based on the untrustworthy relay terminals operate in half-duplex, full-duplex, and hybrid modes. The investigation considers a dual-hop one/two-way half/full-duplex wireless relaying network in the system model. The investigation also considers that a finite number of friendly jammers affect the untrustworthy relay terminals. According to analytical, asymptotic, and Monte Carlo simulation results, the LR-based untrustworthy relay selection strategies achieve cooperative diversity order in high-signal-to-noise ratio.However, friendly jammers and loop interference severely affect the system performance and degrade the achievable diversity order from M to 0 and also cause system coding gain losses. In addition, friendly jammers and loop interference also degrade the system achievable rate performance and cause saturation in high SNRs.Trans Emerging Tel Tech. 2019;30:e3755.wileyonlinelibrary.com/journal/ett

“…By using energy harvesting to augment the battery usage, vital data can be sent from inaccessible sensor nodes. In other aspect, the bidirectional relaying networks that are similar to the model in Zeng et al 19 have also been analyzed thoroughly to derive the outage probability for Rayleigh fading channel in Ozduran et al 20,21 Ozduran and Yarman 20 investigated the impact of cochannel interferences in the bidirectional relaying networks with multiple users supported by single bidirectional relay.

In this paper, we apply the power splitting-based energy-harvesting protocol to enhance the transmission between a wireless access point and a mobile user via a helping relay. The mobile user exploits the energy supplied by the access point and forwarded by the relay to transmit its own data back to the access point, again with the helping of the relay. Here, the effect of various system parameters, including power-splitting factor and the power-to-noise ratio on the system performance, is rigorously studied, with closed-form expressions for the outage probability and system throughput as the results. Furthermore, we figure out the optimal power-splitting ratio at which the information throughput from the user to the AP is maximized, subject to the constraint on the transmitting power at the access point. All above analytical results are also supported by Monte Carlo simulation.KEYWORDS amplify and forward, bidirectional relay, decode and forward, energy harvesting, power splitting

“…1,2 Detailed discussion about the cooperative diversity is given in previous studies. [3][4][5][6][7] Out of the several relaying schemes discussed in the literature, amplify and forward (AF) and decode and forward (DF) are most commonly preferred. From the computational simplicity and low latency perspective, AF is preferred over DF; however, DF relaying's bit error rate performance is better than AF specially at the high signal-to-noise ratio (SNR).…”

SummaryIn this paper, performance of an orthogonal frequency division multiplexing-based variable-gain amplify and forward cooperative system using multiple relay with relay selection is analyzed over independent but not necessarily identically distributed frequency selective Nakagami-m fading channels. For the analysis, nonlinear power amplifier is considered at the relay, and selection combining is adopted at destination node. Closed-form expressions of the outage probability for various threshold signal-to-noise ratio (SNR) values and average symbol error rate for M-ary quadrature amplitude modulation techniques are derived for the considered system. Further, the outage probability analysis is performed in high SNR regime to obtain the diversity order. Furthermore, impact of different fading parameters, multiple relay, and nonlinear power amplifier is highlighted on the outage probability and asymptotic outage probability for various threshold SNRs and on the average symbol error rate for various quadrature amplitude modulation constellations. The derived analytical expressions are generalized for various fading environments while considering the integer-valued fading parameters. Finally, all the analytical results are verified through the Monte Carlo simulations for various SNR levels and system configurations.
