摘要

星地融合无线网络（STIN）是实现全球无缝立体覆盖的重要途径。为指导星地融合无线网络实际部署，对上行覆盖性能成因规律进行分析。利用随机几何对星地异频部署场景进行了建模，其中，卫星在轨道上服从一维泊松点过程（PPP）分布，地面基站和用户服从二维PPP分布。基于此，推导了星地融合无线网络上行覆盖概率关于基站密度、轨道倾角等参数的表达式。实验仿真验证了理论推导结果的正确性，并分析了网络设计参数对上行覆盖概率的影响。

Abstract

Satellite-terrestrial integrated wireless network (STIN) is a pivotal approach in achieving worldwide wireless connectivity. To guide base stations deployment of STIN

an analysis of the uplink coverage probability was conducted. Stochastic geometry was used to modeled the STIN under a setting of distinct frequencies. The satellite stations modeled as a one-dimensional Poisson point process (PPP) on orbit

base stations and users were represented as two-dimensional PPP. The expression for the uplink coverage probability was derived in terms of parameters such as base station density and orbital inclination. The correctness of the derived expression was verified through experimental simulations

and the impact of network parameters on the uplink coverage probability were analyzed.
