“…13 Against this backdrop, harvest energy through radio frequency (RF) signal have been recommended for terrestrial energy limited devices as it includes both information and energy concurrently. 14 Based totally on this, the time splitting relaying protocol and power splitting relaying protocol have been proposed as the two realistic protocols to reap energy from RF signals. For the TSR, receiver allocates some time frame for energy harvesting and the other time for data processing.…”

In this paper, the security performance of a hybrid satellite‐terrestrial cooperative network (HSTCN) with untrusted energy limited relay and imperfect channel state information (CSI) is investigated. The satellite and terrestrial links are assumed to follow Shadowed‐Rician fading and Rayleigh fading distributions respectively. The amplify‐and‐forward energy‐limited relay node employs power splitting relaying mode to scavenge energy from its received signals. By considering imperfect CSI between the relay and destination link, maximum ratio combining (MRC) and selection combining (SC) diversity schemes are utilized at the destination to enhance the quality of received signal‐to‐noise ratio (SNR) and aid jamming signal to prevent the untrusted relay from intercepting the satellite confidential data. Thus, to evaluate the HSTCN security performance, the exact analytical closed‐form expressions for the security outage probability (SOP) and connectivity outage probability (COP) are derived for each of the diversity combining techniques. Owing to trade‐off between SOP and COP, the effective secrecy throughput (EST) expression is obtained for the considered diversity schemes with a view to examine the security and reliability performance of the concerned system. Moreover, the impact of system parameters such as transmit SNR, channel coefficient, energy harvesting coefficient, and number of antennas are evaluated. In addition, the results reveal that the MRC has better SOP, COP, and EST performance compare with the SC. Also, it is found that the system EST degrades at high transmit SNR when the number of antennas at satellite is higher. The accuracy of the derived analytical expressions is confirmed by using Monte‐Carlo simulations.

In this paper, the performance of an Energy Harvesting (EH) enabled full-duplex cooperative decode-and-forward (DF) relaying system is investigated over the Fisher-Snedecor F-fading channel. The system energy-constrained relay unit utilizes time-switching relay protocol for scavenging energy from the source signal and information transmission to the destination. To quantify the system performance, the exact analytical closed-form expression for the system outage probability is derived, and then used to obtain the analytical expression for the average throughput of delay-limited transmission mode. Moreover, the exact closed-form expression for the system Ergodic capacity is derived through which the average delay-tolerant throughput is determined for the system. In addition, the results demonstrate the impact of fading and shadowing severity on the system performance. It also is noticeable from the results that the performance of system is strongly affected by the loop back interference from the relay node. Finally, the accuracy of the derived analytical expressions is then validated through the Monte-Carlo simulation.
