分析了传播环境、小区半径、切换门限等参数对下行容量的影响

并使用计算机仿真对分析结果作了验证.对比表明

该分析结果与计算机仿真所得结果吻合的较好

可以作为分析、设计CDMA网络的基础.

Abstract

An analysis of CDMA downlink capacity is presented in this paper.The analysis is derived from the basic CDMA theory

and is then fitted into the scenario in question with a help of a number of reference simulations.Some results of analysis and simulation are presented.Comparison with the system simulations shows that the analysis result follows well the simulation results.
