  • In this paper, a novel algorithm for distributed power control in cellular CDMA system based on game theory is proposed and an effective cost function is designed for this scheme. Then the existence and uniqueness of the Nash equilibrium are proved for the proposed algorithm. The simulation results show that the proposed algorithm, which compared with several classical distributed algorithms, not only can speed up the convergence but also reduce the transmit power while the terminals are more than 20.
