面向密集城区网络的覆盖预测模型的应用研究

摘要

This article selects statistical model (such as Okumura-Hata model) and deterministic model (such as 3D ray-tracing model) to study the differences of two models in the dense urban area. Then it briefly proposes the application of coverage prediction model for dense urban based practice.%在目前密集城区CDMA无线网络日趋复杂的情况下,如何使覆盖预测与网络实际充分拟合,发挥射频仿真工具在网络优化中的作用,是一个十分值得探讨的课题.本文从密集城区的CDMA无线网络入手,分别选取了统计型模型的Okumura-Hata模型和确定性模型的3D射线跟踪模型进行研究,分析了两种模型在密集城区场景下的差异,最终在实践的基础上提出了面向密集城区的覆盖预测模型的选取方案.
