A Game-Theoretic Power Control Approach for FD Jamming and Interception System Over Rayleigh Fading Channels

This paper addresses the optimum power control problem of Full-Duplex (FD) jamming and interception system under game theory framework over Rayleigh fading channels. First, a game-theoretic power control model is established to describe the interactions between transmitter and FD jammer by exploiting the effective secrecy throughput (EST) as metric in present of residual self-interference (SI). Then, the best response is theoretically defined and derived for the transmitter and FD jammer, more specifically, the existence of Nash equilibrium (NE) is proved and analyzed. Finally, the effectiveness of proposed power control game is validated by the numerical and simulation results, and it is found that a better SI cancellation performance will help the FD jammer achieve better NE performance in the power control game.
