45096 在物理层安全领域，协作中继技术因具备提升网络容量和扩展网络覆盖范围等优点，受到学术界广泛关注。 The cooperative relay technique in the field of physical layer security is widely concerned by the academic community,due to the advantages of increasing the network capacity and expanding the network coverage.
45097 但是，协作中继在某些时候可能存在非可信情形。 However, cooperative relays may play as untrusted nodes in some certain circumstances.
45098 基于此，在瑞利衰落信道下，为提升非可信中继系统安全性能，提出一种多天线全双工目的节点加扰（FDJ, full-duplex destination jamming）策略。 Based on this, to enhance the secrecy performance of untrusted relay systems,a novel full-duplex destination jamming (FDJ) scheme was proposed in the Rayleigh fading channel.
45099 为最大化系统安全容量，针对多天线目的节点提出一种切换分离式最优天线选择（OAS, optimal antenna selection）方案，并设计出信源和目的节点功率分配优化方案，给出相应的安全性能指标闭合表达式。 In order to maximize the systems' secrecy capacity, a switchable split-optimal antenna selection (OAS) scheme was proposed for a multiple-antenna destination,the power allocation optimization scheme between the source and destination was designed, and the corresponding closed-form expressions of secrecy performance were given.
45100 在大规模天线下，推导出 FDJ-OAS 策略的遍历可达安全速率和瞬时安全容量下最优功率分配因子闭合表达式。 In the large-scale antennas analysis, the closed-form expressions of the ergodicachievable secrecy rate and the optimal power allocation factor of instantaneous secrecy capacity for the FDJ-OAS scheme were derived.
45101 在不同的渐近条件下，推导出 FDJ-OAS 策略的安全中断概率的渐近线闭合表达式。 Furthermore, based on different asymptotic cases, the asymptotic analyses of secrecy outage probability for the FDJ-OASscheme were significantly analyzed.
45102 仿真结果显示，理论分析与蒙特卡洛仿真曲线十分吻合， Simulation results show that the analytical curves match well with the Monte-Carlo simulation results.
45103 FDJ-OAS 策略的安全分集阶数与天线数呈正比，可实现天线全分集，凸显了 FDJ-OAS 策略的性能优越性。 It is concluded that the diversity order of the FDJ-OAS scheme is proportional to the number of antennas and antenna diversity can be achieved, which reveals the advantages of the proposed FDJ-OAS scheme.
