چکیده انگلیسی
In order to enhance the anti-jamming capability of Cyberspace data-link (CDL) in the complex electromagnetic environment, the performance of jamming sensing of simultaneous transmit and receive based cognitive anti-jamming (SCAJ) receiver impaired by IQ imbalance is investigated. Firstly, energy detection (ED) based the jamming detection and false-alarm probabilities in closed-form for single- and multi-channel SCAJ receiver are derived. Then, the image channel interference cancellation (IC) scheme is proposed to mitigate the image channel crosstalk. Simulation results show that the false-alarm probability is increased by IQ imbalance, and the proposed interference cancellation scheme can reduce the adverse effect of IQ imbalance, thus the anti-jamming performance of SCAJ receiver in CDL system can be improved.
