Abstract :
[en] This paper utilizes a reconfigurable intelligent sur-face (RIS) to enhance the anti-jamming performance of wirelesscommunications, due to its powerful capability of constructingsmart and reconfigurable radio environment. In order to establishthe practical interactions between the base station (BS) and thejammer, a Bayesian Stackelberg game is formulated, where theBS is the leader and the jammer acts as the follower. Specifically,with the help of a RIS-assisted transmitter, the BS attemptsto reliably convey information to users with maximum utilities,whereas the smart jammer tries to interfere the signal receptionof users with desired energy efficiency (EE) threshold. Since theBS and the jammer are not cooperative parties, the practicalassumption that neither side can obtain the other’s strategies isadopted in the proposed game, and the angular information basedimperfect channel state information (CSI) is also considered.After tackling the practical assumption by using Cauchy-Schwarzinequality and the imperfect angular information by using thediscretization method, the closed-form solution of both sidescan be obtained via the duality optimization theory, whichconstitutes the unique Stackelberg equilibrium (SE). Numericalresults demonstrate the superiority and validity of our proposedrobust schemes over the existing approaches.
