On the performance of full duplex cognitive anti-jamming receiver impaired by phase noise

In this paper, the performance of interference sensing of full duplex cognitive anti-jamming (FCAJ) receiver impaired by phase noise in local oscillators is investigated under fading channel. Firstly, energy detection based the interference signal to noise ratio (INR) of FCAJ receiver with phase noise under different channels is analyzed. Then, the detection and false alarm probabilities in closed-form for FCAJ receiver are derived. Simulation results show that the degradation of the INR due to phase noise is more severe than that due to the channel. And the anti-jamming capability of wideband FCAJ receiver with phase noise outperforms the narrowband receiver at the same operation frequency bands.
