摘要

研究了蜂窝CDMA网络下行链路的功率控制问题。可以看出有两种方法。第一种是使用基地到移动的距离来分配传输功率，而另一种是基于闭环控制。对于CDMA网络的下行链路，评估了PC机的最佳可实现性能。然后研究了一种几乎最优的下行功率控制。为了讨论下行PC机的性能，给出了数值算例。

Power allocation and control for the downlink in cellular CDMA networks

The issue of power control (PC) in the downlink of a cellular CDMA network is studied. Two approaches are discernible. The first uses the base-to-mobile-distance in order to allocate transmitted powers while the other is based on closed-loop control. The best achievable performance of a PC is evaluated for the downlink of a CDMA network. This paper then studies an almost optimal downlink power control. Numerical examples are presented in order to discuss the downlink PC performance.
