Cooperative communication systems with wireless power transfer are being investigated for future advanced wireless networks. In this research, we propose applying a wireless power transfer to dual-hop cooperative communication systems, in which a relay node harvests the energy from the radiofrequency in order to forward the received signal, and a source node can communicate with a destination node directly or through the selected relay nodes. The system performance is evaluated by an outage probability that is calculated over independent and identically distributed (i.i.d) Nakagami-m distributions in two scenarios, i.e., integer m and arbitrary m. Furthermore, the closed forms of the outage probability expressions are derived in the case of both the amplify-and-forward (AF) and decode-and-forward (DF) protocols. The Monte Carlo method is utilized to simulate the system with the aims of evaluating the system performance and verifying the theoretical analysis. The numerical results highlight that the proposed calculation method and the closed form of the outage probability are accurate. We also compare the system performance of both the AF and DF protocols and show the effect of parameter m on the performance of the system.

正在研究具有无线电力传输的协作通信系统，以用于未来的高级无线网络。在这项研究中，我们建议将无线电力传输应用于双跳协作通信系统，在该系统中，中继节点从射频中获取能量以转发接收到的信号，而源节点可以与目标节点直接通信，也可以与目标节点进行通信。通过选定的中继节点。系统性能是由计算在独立同分布（iid）Nakagami-停用概率评价米分布在两种情况下，即，整数米和任意米。此外，在放大转发（AF）和解码转发（DF）协议的情况下，都可以得出中断概率表达式的闭合形式。蒙特卡罗方法被用来模拟系统，目的是评估系统性能并验证理论分析。数值结果表明，所提出的计算方法和停机概率的闭合形式是准确的。我们还比较了AF和DF协议的系统性能，并显示了参数m对系统性能的影响。
