摘　　要：本文就ＣＤＭＡ蜂窝系统中的功率控制问题进行了讨论，其中包括功率控制误差的考虑以及功率控制源的选择．在以往的分析中，常常只考虑基于距离的功率选择．本文引入了对实际环境下基于导频功率的选择考虑，给出了两种方法的比较．Power control in CDMA cellular system is discussed in this paper.Consideration on power control error(PCE) and selection of power control source are taken into account.In the previous analyses,distance based selection on power control source was assumed for simplification.This paper considers pilot power based selection under practical environment and makes comparison between these two methods.Numerical results show that the latter method improves the system capacity.
