Abstract
In order to enhance the anti-jamming capability of simultaneous transmit and receive based cognitive anti-jamming (SCAJ) communication system in the complex electromagnetic environment, an improved spectrum sensing scheme based on energy detection (IED) is proposed in this paper. For the SCAJ receiver using the IED scheme, the closed expression of jamming detection and false alarm probability under Rayleigh fading channels is derived, and the outage probability of SCAJ system is analyzed. Simulation results show that the effect impacted by self-interference (SI) at SCAJ receiver can be suppressed and the outage performance of SCAJ system is improved by the proposed IED scheme.
