Abstract: 
We consider a cooperative system consisting of a source node, a destination node, N (N>1) wireless-powered relays, and an eavesdropper. Each relay is assumed to be with a nonlinear energy harvester, in which there exists a saturation threshold, limiting the level of the harvested power. For decode-and-forward and power splitting protocols, the Kth best relay is selected to assist the source-relay-destination transmission. An analytical expression for the secrecy outage probability is derived, and also verified by simulation.

基于非线性能量收集器的无线充电中继系统保密中断性能分析

概要:本文考虑了一个包含单一信源、单一信宿、N(N>1)个无线充电中继和单一窃听者的协作系统。本文假设每个中继都拥有一个非线性的能量收集器,且该能量收集器存在一个饱和阈值以限制收集能量的大小。在考虑解码转发和功率分配接收器的场景中,本文选择第K个最优中继来协助信源–中继–信宿链路的传输。同时,本文还推导了保密中断概率的解析表达式,并通过仿真验证了分析结果。

关键词:解码转发;能量收集;非线性;保密中断概率
