On Secrecy Performance for Energy-Harvesting Multi-Antenna Relaying Networks with a Dual-Use Source

Zhang J., Pan G., Xie Y.

International Journal of Electronics and Telecommunications

2018

Vol. 64, No. 1

This paper studies the secrecy performance of an energy-harvesting relaying system in the presence of a dualuse source node and an eavesdropper. Specifically, the source has dual roles in the dual-hop communication: 1) to transmit confidential information in the first hop; 2) to generate jamming signal to interfere the eavesdropper in the second hop. Moreover, the multi-antenna relay deploys a power-splitting harvesting scheme to coordinate the information receiving and energy harvesting, and adopts maximal ratio combining technique to process the multiple copies of signals. Considering decode-andforward protocol and transmit antenna selection scheme, we derive an analytical expression for secrecy outage probability, and perform Monte Carlo simulation to validate the analysis. Analytical results show that the SOP performance with the dualuse source node can be effectively improved when the relaydestination channel does not have absolute advantage over the relay-eavesdropper channel.

Performance analysis of cooperative non-regenerative transmission system operating over Nakagami-q (Hoyt) fading channels will be presented in this paper. Usage of Maximal Ratio Combining (MRC) space diversity technique at the reception will be considered. Closed form expression will be provided for the moment generating function (MGF) of the received signal-to-noise ratio (SNR). Capitalizing on this, standard performance measure, average symbol error probability (ASEP) over various modulation formats will be efficiently evaluated. Obtained numerical results will be graphically presented in order to show the influence of system parameters, like fading severity and reception diversity order on overall system performances.

Przeanalizowano kooperacyjny system transmisji wykorzystujący kanał Nagakami-q (Hoyt). Rozważono użycie techniki Maximal Ratio Combining (MRC). Przedstawiono przykład ilustrujący wpływ parametrów transmisji, takich jak zróżnicowanie zaniku (fading severity) czy różnorodność porządku odczytu (reception diversity order) na możliwości systemu.
