The aim of this article is to investigate the outage performance of nonlinear radio frequency (RF) energy harvesting (EH) enabled decode‐and‐forward relay assisted cognitive radio network. Here, secondary transmitter (ST) can access the licensed spectrum of primary users (PUs) to send its message toward the secondary receiver and at the same time, it can support the primary communication by performing like a relay node. ST can harvest the energy from the received RF signal of primary transmitter to execute its necessary activities. The closed‐form expressions of PU and secondary user outage are derived to measure the end‐to‐end reliability of the system. The accuracy of derived expressions are also validated through the observation of simulation results. In addition to that, the performance of nonlinear EH model is also compared with respect to linear EH model.

基于认知无线电网络中基于非线性射频能量收集的协作通信的中断分析

本文的目的是研究非线性射频（RF）能量收集（EH）启用的解码和转发中继辅助认知无线电网络的中断性能。在此，辅助发送器（ST）可以访问主要用户（PU）的许可频谱，以将其消息发送到辅助接收器，同时，它可以像中继节点一样支持主要通信。ST可以从接收到的主发射机的RF信号中收集能量，以执行其必要的活动。得出PU和辅助用户中断的封闭式表达式，以衡量系统的端到端可靠性。通过观察模拟结果也可以验证派生表达式的准确性。在此之上，
