摘　　要：在CDMA系统中，导频功率比是一个重要的工程设计参数，能否正确的选取导频功率比将直接影响系统性能和链路容量。文中就导频功率比对系统容量及平衡的影响进行了探讨和研究，给出了满足链路平衡条件下恰当的导频功率比范围。In CDMA mobile network, pilot to powerratio is an important parameter of engineering design. The proper selection of pilot to powerratio directly affects the system performance and link capacity. This paper discusses the capacity and link-balance impact of pilot to powerratio, and gives an adequate pilot to powerratio percentage under link-balance condition.
