| 摘 要： | 为了增强复杂电磁环境中网电空间数据链的抗干扰能力，提出了基于发送-感知-接收（T-S-R）工作模式的同时收发认知抗干扰（SCAJ）技术，通过在感知/接收周期内动态分配感知、接收时隙而实现实时抗干扰。针对所提同时收发抗干扰策略，研究了基于能量检测的干扰感知性能，推导出衰落信道下干扰检测概率的闭式表达，并分析了同时收发认知抗干扰系统容量。仿真结果表明，提出的同时收发认知抗干扰技术提升了网电空间数据链的干扰感知能力，且在自干扰较低时能够提高网电空间数据链系统容量。

| Abstract: | In order to enhance the anti-jamming capability of cyberspace data-link in the complex electromagnetic environment, a simultaneous transmit and receive cognitive anti-jamming (SCAJ) strategy based on transmit-sense-receive mode is proposed in this paper. Real time anti-jamming can be achieved by dynamically allocating the sensing timeslot and receiving timeslot. We study the jamming sensing performance of the proposed SCAJ scheme based on energy detection. The closed expression of jamming detection probability under fading channels is derived, and the system capacity of SCAJ is analyzed. Simulation results show that the proposed SCAJ technology can enhance the jamming sensing capability of cyberspace data-link and improve the system capacity in the region with low self-interference. |
