摘　　要：该文主要研究了基于第三代移动通信系统的功率控制问题。提出了一种基于估计器的闭环分布式功率控制方法,先从理论上对其进行了性能分析,然后给出了系统解决方案,最后建立系统模型并进行了系统仿真,仿真结果证明了该功率控制方法具有快速的收敛性,对信道有较强的跟踪特性,具有很好的应用前景。This paper investigates the power control used in 3G. Then, presents a closed-loop distribution power control method based on estimator. Firstly the performance of this method is analyzed in theory, and a set of systematic scheme is given, Secondly a system model is established. Finally simulation results show that the convergence speed of this method is fast. The result is a strong ability of tracing wireless channel. So this method possesses a good perspective.
