摘要：

针对多中继传输系统在同信道干扰下面临的保密信息安全传输和系统节点能量受限的问题, 提出了一种联合中继选择和基于能量采集的友好干扰机辅助的物理层安全传输方案。首先, 建立基于解码转发(decode-and-forward, DF)中继模式的多中继系统模型。其次, 当发射机仅获得部分信道状态信息时, 在第一时隙, 以最大化系统保密容量为目标, 给出了一种最佳中继节点选择策略。同时, 友好干扰机基于功率分裂(power splitting, PS)协议从合法信号和同信道干扰中采集能量。在第二时隙, 友好干扰机利用采集的能量, 向窃听者发送人工噪声, 进行协作干扰, 从而实现两个时隙保密信息的传输。接着, 推导了系统的保密中断概率闭合表达式。最后, 利用蒙特卡罗仿真方法分析了发射信噪比、同信道干扰源数目及干扰信噪比等参数对系统保密性能的影响, 验证了理论推导的正确性, 仿真结果显示所提方案具有更优的保密性能。

Abstract:

The physical-layer security (PLS) transmission scheme joint with relay selection and friendly jammer-assisted based on energy harvesting (EH) is proposed to solve the energy-constrained system nodes and confidential signal security commission issues upon the multi-relay transmission system with multiple co-channel interferences. Firstly, a multi-relay system model based on decode-and-forward (DF) relay mode is established. Then, when the transmitter obtains only part of the channel state information. In the first time slot, the optimal relay selection scheme is proposed to maximize the secrecy capacity of the system. Simultaneously, friendly jammer harvests energy from the legitimate signals and co-channel interferences based on power splitting (PS) protocol in this phase. In the second time slot, the harvested energy by friendly jammer is used to send artificial noise(AN) to eavesdropper for cooperative jamming, to realize the transmission of confidential information in two time slots. Additionally, the closed-form expression of the system secrecy outage probability is derived. Finally, the Monte Carlo simulations method is used to analyze the influence of emission signal-to-noise ratio, the number of co-channel interferences, and the interference-to-noise ratio of co-channel interferences on the secrecy performance of the system. The correctness of the theoretical derivation is verified, and the simulation results show that the proposed scheme has a better secrecy performance.

Key words: physical-layer security, co-channel interference, relay selection, cooperative jamming, energy harvesting, secrecy outage probability
