| 摘 要： | 分析了认知无线电（Cognitive Radio，CR）非正交多址（Non-orthogonal Multiple Access，NOMA）网络中的物理层安全性能。考虑到现有窃听者，支持NOMA的CR通过Nakagami-m信道以解码转发协作模式传输数据。为了分析CR-NOMA物理层安全性能，通过连接中断概率和安全中断概率的闭式表达式来评估CR-NOMA的安全性能。此外，通过蒙特卡罗模拟仿真以验证推导出的分析结果，并深入分析了参数对系统性能的影响。

| Abstract: | The physical layer security(PLS) in cognitive radio(CR) networks based on non-orthogonal multiple access(NOMA) network is analyzed.Considering an existing eavesdropper,the NOMA-based CR transferes data with the decode-and-forward collaborative mode over Nakagami-m channel.To analyze the performance of NOMA-based CR networks in PLS perspective,the security performance is evaluated by the closed-form expressions for connection outage probability and secrecy outage probability.Furthermore,Monte Carlo simulations are provided to verify the derived analytical results and the impact of parameters on system performance is analyzed. |
