摘要

本文利用随机几何理论研究了具有多用户干扰的自主飞行器（AAV）网络中上行信噪比（SIR）的元分布。在具有最强平均接收信号强度（RSS）关联策略的多AAV和多地面用户（GUs）网络中，我们将AAV位置和GU位置建模为两个泊松点过程，并推导出上行SIR满足给定覆盖阈值概率的n阶矩。由于上行SIR元分布的解析形式难以计算，为了获得易于处理的理论结果，我们将其近似为beta分布。数值结果验证了上行链路SIR元分布近似公式在不同网络部署场景下的准确性。该公式可用于估算特定AAV网络的最佳AAV高度/密度，为实际AAV网络部署提供指导。

Performance of AAV Networks With Multi-User Interference: A Meta Distribution Analysis

This letter studies the meta distribution of uplink signal-to-interference ratio (SIR) in autonomous aerial vehicles (AAV) networks with multi-user interference by stochastic geometry theory. In a multiple AAV and multiple ground users (GUs) network with the strongest average received signal strength (RSS) association policy, we model the AAV locations and GU locations as two Poisson point processes and derive the nth moment of the probability of uplink SIR satisfying a given coverage threshold. Since the analytical form of the uplink SIR meta distribution is hard to calculate, we approximate it by the beta distribution to obtain tractable theoretical results. The numerical results validate the accuracy of the approximated formula of the uplink SIR meta distribution in varying network deployment scenarios. Our formula can be used to estimate optimal AAV altitude/density for specific AAV networks, providing guidelines for practical AAV network deployment.
