摘要

在以对数正态衰落信道为特征的室内无线信道中，中继节点和目的节点同时存在干扰信号，在中继节点通过收集环境干扰信号的能量来利用无线供电方案，研究了具有干扰的无线供电协作系统的中断性能。在机会式解码转发(DF)方案下，源节点向中继节点和目的节点广播1位导频信号。在目标节点1位反馈信号的基础上，系统将工作在直连模式(direct link mode, DLM)或协同中继模式(cooperative relay mode, CRM)。导出了中断概率的解析表达式。数值结果证实了几个关键参数对系统性能的影响。

Performance Analysis for an Opportunistic DF Based WPC System with Interferers over Log-Normal Fading Channels

In this paper, we are dedicated to investigating the outage performance of wireless powered cooperative (WPC) system with interferers over indoor wireless channels characterized by log-normal fading channels, where the relay node and the destination node also exist jamming signals and wireless powered scheme is exploited at the relay node by harvesting energy from ambient jamming signals. Under the opportunistic decode-and-forward (DF) scheme, the source node will broadcast 1-bit pilot signal to the relay node and the destination node. On the basic of the 1-bit feedback signal from the destination node, the system will work in direct link mode (DLM) or cooperative relaying mode (CRM). Analytical expression of outage probability is derived. Numerical results corroborate the impacts of several key parameters on the system performance.
