A Pricing Function Based Power Control Game Algorithm for Cognitive Radio
Feng Tian · Journal of Nanjing University of Posts and Telecommunications · 2010
Based on the non-cooperative power control game(NPG) proposed by David Goodman.,an improved pricing function is adopted and a power control game algorithm suitable for cognitive radio system is proposed.Then the existence and uniqueness of the Nash equilibrium are proved for the proposed algorithm.The simulation results have shown that,in comparison to several classical distributed algorithms,the proposed algorithm not only reduces the transmit power and improves the user's utility but also speeds up the convergence.Therefore it fits well to the cognitive radio system with high demand of time-delay characteristic.
