摘要
CDMA蜂窝网中存在远近效应，必须引入功率控制。功率控制对系统容量有极大的关系，本文将着重研究功率控制精度对系统容量的影响，提出功率控制的高斯误差分布假设，并得到系统容量随功率控制变化的规律及可参考的计算方法。
CDMA Cellular networks can produce short-term and long-term effects,so power control will have to be exercised.In fact,power control has great relation to the system capacity.This paper focuses on the effects of the precision of power control on the system capacity,puts forward the assumption that the distribution of any signal is Gaussian,works out the law that the system capacity vares with power control,and proposes a calculation method for reference.
