Abstract :
In cognitive radio (CR), interference alignment (IA) is an effective approach to eliminate the interference of secondary users (SUs). Thus, SUs can share the spectrum with primary users (PUs). In this paper, IA for overlay CR is discussed, and a time resource auction scheme based on game theory is proposed, which uses the given related equilibrium functions to balance the benefits of PU and SUs, meanwhile the time resource can be reasonably distributed. Simulation results are presented to show the effectiveness of the proposed scheme.
