无人机AeroMACS数据链路分析
Analysis of AeroMACS Data Link for Unmanned Aircraft Vehicles
摘要：
航空移动机场通信系统（AeroMACS）基于通常称为WiMAX的IEEE 802.16e移动无线标准。预计它将成为下一代航空通信系统的主要部分，以支持载人和无人应用的固定和移动服务。AeroMACS将是一项重要的技术，有助于为无人机（UAV）全面融入国家领空铺平道路。到目前为止，已经对AeroMACS进行了一些实际测试和分析。本文的主要贡献是考虑其功能背后的理论概念，并讨论其适用于无人机应用。AeroMACS物理层框架的数学分析提供了理论上的权衡。主要分析了AeroMACS OFDMA结构对速率限制、小区覆盖、信道估计要求和载波间干扰的影响。
英文摘要：
Aeronautical Mobile Airport Communications System (AeroMACS) is based on the IEEE 802.16e mobile wireless standard commonly known as WiMAX. It is expected to be the main part of the next-generation aviation communication system to support fixed and mobile services for manned and unmanned applications. AeroMACS will be an essential technology helping pave the way toward full integration of Unmanned Aircraft Vehicle (UAV) into the national airspace. A number of practical tests and analyses have been done so far for AeroMACS. The main contribution of this paper is to consider the theoretical concepts behind its features and discuss their suitability for UAV applications. Mathematical analyses of the AeroMACS physical layer framework are provided to show the theoretical trade-offs. We mainly focus on the analysis of the AeroMACS OFDMA structure, which affects the speed limits, coverage cell, channel estimation requirements, and inter-carrier interference.
