Abstract

This paper presents a novel scheme of Interference-aided RF Energy Harvesting in Cooperative NOMA system in presence of an Eavesdropper. Basic objective of this paper is to investigate the secrecy performance under the influence of a cluster of interferers under jamming cancellation scheme. The influence of various network parameters such as the Transmit Source Power, Nakagami-m parameter, Jamming Signal Power and the number of co-channel interferers on the system secrecy performance has been evaluated. Additionally, the impact of Power allocation Factor for varying Transmit Power of Source on the Ergodic Secrecy Rate has been found. The results of this paper illustrate how the jamming and interference power affect the secrecy performance. Furthermore, an optimal value of Source Signal-to-Interference-Noise Ratio at which the Secrecy Outage Probability is minimized has been found out for variation of Jamming and Interference Power Levels. This study can serve as a constraint on the optimal number of interfering nodes that can be utilized for energy harvesting to achieve a desired level of secrecy.

一种新的协同NOMA网络干扰辅助射频能量收集方案

本文提出了一种存在窃听者的协同NOMA系统中干扰辅助射频能量收集的新方案。本文的基本目的是研究在干扰消除方案下，在一簇干扰影响下的保密性能。分析了发射源功率、中源参数、干扰信号功率和同信道干扰数等网络参数对系统保密性能的影响。此外，还发现了不同发射功率时功率分配系数对遍历保密率的影响。本文的研究结果说明了干扰和干扰功率对保密性能的影响。在此基础上，针对干扰和干扰功率的变化，求出了使保密中断概率最小的源信噪比的最优值。本研究可作为约束能量收集所需的干扰节点的最佳数量，以达到所需的保密水平。
