摘要:
该文针对干扰源以及窃听节点均随机分布的通信场景，分析了认知无线电启发式非正交多址接入(CR-NOMA)网络中次用户通信对的安全通信性能。采用随机几何理论，将窃听节点和干扰节点建模为服从特定分布的齐次泊松点过程(PPP)。首先，在保证主用户通信对通信可靠性的前提下，得到了发端设定的功率分配系数，进一步得到了次用户通信对的连接中断概率和安全中断概率的闭式表达式。随后，得到了功率分配系数随主用户可靠性能约束的变化规律。最后，研究了次用户对的中断概率随着窃听节点密度、发端发送功率的变化情况，结果表明干扰信号的增强在降低网络可靠性能的同时，换来了安全性能的提高。仿真结果验证了理论分析的正确性。

Abstract:This paper analyzes the security communication performance of secondary user communication pairs in Cognitive Radio Non-Orthogonal Multiple Access (CR-NOMA) networks, where interference sources and eavesdropping nodes are randomly distributed. The stochastic geometry theory is used to model the eavesdropping nodes and the interfering nodes as a homogeneous Poisson Point Processes (PPP). Firstly, to ensure the reliability of the primary user communication pairs, the power allocation coefficient set of the sender is obtained, and the closed expressions of the connection outage probability and the secrecy outage probability of the secondary user are further obtained. Then, the variation of the power distribution coefficient with the constraint of the primary user’s reliability is analyzed. Finally, the relationship between outage probability of secondary user communication pairs and the density of the eavesdropping nodes and the transmission power is studied. The research shows that the enhancement of interfering signal reduces the reliability of the system, but brings about a significant improvement of security performance. The simulation results verify the correctness of the theoretical analysis.
