基于中继联合优化选择的物理层安全方案
Physical Layer Security Scheme Based on Jointly Optimal Relay Selection
摘要
Abstract
To improve the security level of information transmission in Cognitive Radio (CR) networks, a physical layer security scheme based on jointly optimal transmission relay and interference relay selection is proposed. This paper considers a primary network in coexistence with a secondary network, the cooperative transmission relay and the cooperative interference relay are optimized to realize the secure transmission of information. Derive closed-form expression of the secrecy outage probability of the proposed scheme under the condition of Rayleigh fading channels.Simulation results show that the scheme can achieve lower average secrecy outage probability in different scenarios, and improve the security performance of CR networks.关键词
