Abstract

In wireless cellular communication, it is essential to find effective means for power control of signals received from randomly dispersed users. In this paper, a novel distributed power control game algorithm, focusing on cellular CDMA system, was proposed by designing an effective cost function. The simulation results show that the proposed algorithm, compared with other three algorithms, not only can obtain faster convergence but also have higher average SIR while the number of mobiles is less than 20.
