Abstract

In this letter, we consider a hybrid GEO-LEO satellite network where GEO and LEO satellites are distributed according to independent Poisson point processes and share the same frequency resources. We first analyze satellite-visible probabilities, distance distributions, and association probabilities. Then, we derive an analytical expression for the network’s coverage probability. Through Monte Carlo simulations, we verify the analytical results and demonstrate the impact of system parameters on coverage performance. The analytical results effectively estimate the coverage performance in scenarios where GEO and LEO satellites cooperate or share the same resource.

GEO-LEO混合卫星网络建模与分析

本文考虑GEO-LEO混合卫星网络，其中GEO和LEO卫星按独立泊松点过程分布，共享相同的频率资源。我们首先分析卫星可见概率、距离分布和关联概率。然后，推导出网络覆盖概率的解析表达式。通过蒙特卡罗仿真验证了分析结果，并展示了系统参数对覆盖性能的影响。分析结果有效地估计了GEO和LEO卫星合作或共享相同资源情况下的覆盖性能。

期刊介绍： The IEEE Communications Letters publishes short papers in a rapid publication cycle on advances in the state-of-the-art of communication over different media and channels including wire, underground, waveguide, optical fiber, and storage channels. Both theoretical contributions (including new techniques, concepts, and analyses) and practical contributions (including system experiments and prototypes, and new applications) are encouraged. This journal focuses on the physical layer and the link layer of communication systems.
