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.
