摘　　要：分析了cdma2000-1x系统的前向信道发射功率分配。通过仿真试验及理论推导,给出了导频信道和业务信道信号质量之间的相互依赖关系并绘出导频信号和业务信道之间的相关性曲线;根据这种相关性曲线,从而发现使总发射功率最小的最佳导频功率;最后提出并分析了高速补充信道对cdma2000-1x前向链路功率分配的影响。This paper analyzes the forward link power allocation for cdma2000-1x. With the simulation test and theory deduction, the paper gives the dependency of the signal qualities between pilot channel and traffic channel, the graphics of their dependency is also plotted. The optimal pilot signal quality is found which minimizes the total transmit power based on the graphics. We also show and analyze the effect of high rate supplementary channel for cdma2000-1x forward link power allocation.
