摘要
CDMA系统由于频率复用 ,以及无线信道的衰落等原因 ,存在“边缘效应”和“远近效应”,降低干扰可以直接增加 CDMA系统的通信容量 ,功率控制技术即是一种有效的方法。本文详细阐述了 CDMA系统中功率控制的原理 。
There are edge effect and near-far effect in CDMA system for the reason of frequency reuse and wireless channel fading .To decrease the interference can increase the capacity of CDMA system. Power control is an important and available technique. This paper in details introduces the operation principle, chief algorithm, current problem and correlative resolve method of power control.
