Power Control Game Algorithm Based on Combination Pricing Function

Based on the non-cooperative power control game (NPG) algorithm, the utility and pricing function are analyzed, then the combination pricing function is proposed and power control game algorithm suitable for cognitive radio (CR) networks is realized, the existence and uniqueness of the Nash equilibrium are proved for proposed algorithm. Simulation results show that the proposed algorithm can balance the interests of the CR users themselves, reduce the whole system of interference and improve the performance of cognitive radio system.
