Abstract: A new power control algorithm in CDMA system is proposed in this paper, based on the analysis of the traditional algorithm's shortcoming, the parameters optimization in the fuzzy control system are considered. The simulation results show that the control precision can be improved by 0.6-1.1dB with 3-path diversity and 5 fuzzy sets distribution. The performance of the proposed algorithm under different limited word length condition are also analyzed.
