Abstract

This letter studies power control for a two-hop interference channel. An innovative solution based on mixed strategy game theory is proposed to enable the users to transmit probabilistically. This creates orthogonal transmission opportunities and thus boosts the system throughput through interference avoidance. The existence, uniqueness, and stability of the Nash equilibrium are established. Simulation results show significant rate enhancement over the existing deterministic approach.
