摘要
本文提出了一种在多径传输约束条件及不同的移动台运动速度条件下对前向信道链路进行功率分配的方法 ,这是根据导频信道和业务信道之间各自信号强度的相关性合理地分配前向链路中的信道发射功率 .通过实验测试及理论推导 ,本文给出了这种相关性曲线 ,从而发现了最佳的导频信道功率 ,它能够在满足 1%FER时使总发射功率最小 .
This paper proposes a method for allocating the transmit power on cdma2000 1x forward link channel under the conditions of multi path and different rate,i.e.,based on the dependency that exists between the respective signal qualities of the pilot channel and traffic channels to allocate the forward link power reasonably.With laboratory test and theory deduction,the paper gives the graphics of their dependency,and then an optimal pilot signal quality is found which minimizes the total transmit power under the condition of 1%FER.
