A game-theoretic approach based on pricing scheme on the two-user Gaussian interference channel

In this work, a non-cooperative power control game between two selfish users over a Gaussian interference channel is presented. In this proposed scenario each user is willing to maximize its utility under power constraints in transmitters. The outcome of this non-cooperative game is considered. We show that by choosing a proper price for each of the users, the outcome of the game is a unique, Pareto-efficient and proportional fair Nash Equilibrium (NE). Numerical Results confirm our analytical developments.
