【摘要】 CDMA系统的容量优势需要通过合理的规划来实现。本文对 CDMA无线网络小区规划中的核心问题——覆盖和容量的关系问题进行了讨论。在对软切换概率和软切换下中断概率进行分析的基础上 ,将现有的单小区下的中断概率分析扩展到了多小区下。在此基础上 ,引入空间 Poisson过程描述用户数的时间和空间分布 ,并对均匀和非均匀分布情况进行了相应分析 ,导出了相应的单小区和多小区下的覆盖与容量的关系。有关理论结果可以应用于实际小区规划更多还原

【Abstract】 Feasible cellular planning is needed to realize the overwhelming advantage of CDMA on capacity. In this paper, we investigate the relationship of coverage and capacity of a CDMA cell, which is the core of the cellular planning of CDMA wireless network. Based on the previous works on single cell case, we extend the outage probability analysis to the multi-cell environment with soft-handoff by analyzing the outage probability under soft-handoff and the soft-handoff probability. Furthermore, a spatial Poisson process is introduced to describe the temporal and spatial distribution of mobiles. Both uniform and non-uniform distributions of subscribers are analyzed. And based on this we make a derivation of a tradeoff between coverage and capacity in single and multi-cell environments. The above work makes the theoretical results practical in cellular planning of CDMA wireless network.更多还原
