摘　　要：针对复杂战场环境中存在敌方干扰的情形,文章分别考虑中继采用放大转发(AF)和模拟网络编码(ANC)两种方案的抗单音干扰性能。通过分析表明:协同方式可以明显降低干扰造成系统中断性能的"平底效应",协同AF和协同网络编码(CNC)相对非协同方式具有一定的抗干扰性能。固定信干比条件下,CNC比协同AF更适宜传输高速率数据。在固定数据速率时,CNC协议中断性能优于协同AF。To tackle the hostile jamming in the battlefield, the paper analyzed and compared the anti-jamming performance between the Amplify-and-Forward（AF） and Analog Network Coding （ANC） in the presence of single-tone interference. This theoretical analysis and simulations demonstrate that cooperation can effectively improve ＂the floor effect＂ of the outage performance resulting from hostile jamming. Besides, compared with the systems without cooperation, cooperative systems based on either AF or cooperative network coding both have the capability of antijamming to some extent and that the latter has better performance when transmitting high speed data with fixed signal-to-interference ratio. Furthermore, with fixed data rate the higher SIR brings better anti-jamming performance to both schemes.
