摘要

作为地面移动通信网络的补充，低轨卫星互联网已成为全球航天和通信领域的重要发展方向，以Starlink和OneWeb为代表的国外低轨星座已率先提供商用服务。面对建设天地一体化信息网络的重大机遇和挑战，能够兼容地面移动通信和卫星通信的信号波形是实现星地融合通信的关键技术之一。针对OneWeb低轨星座信号波形，研究解析其帧结构和细节要点，由此分析OneWeb信号波形的关键设计参数和核心设计思路，并将OneWeb信号波形与4G/5G、数字视频广播（digital video broadcasting，DVB）等典型信号波形进行对比分析，这对我国卫星互联网星座的信号波形设计和工程实现具有一定参考价值。

Abstract

As a supplement to terrestrial mobile communication networks

low earth orbit (LEO) satellite Internet has become an important development direction in the global aerospace and communications fields. Foreign LEO constellations represented by Starlink and OneWeb have begun to provide commercial services. Faced with important opportunities and challenges in building a space-integrated-ground information network

the signal waveform that can be compatible with both terrestrial mobile communication and satellite communication is one of the key technologies for achieving satellite-terrestrial integrated communication. Aiming at the signal waveform of the OneWeb LEO constellation

its frame structure and key details are studied and analyzed. Based on this

the key design parameters and core design ideas of the OneWeb signal waveform are analyzed. Furthermore

a comparative analysis is conducted between the OneWeb signal waveform and typical signal waveforms such as 4G/5G and DVB. The analysis provides certain reference and application value for the signal waveform design and engineering implementation of China's satellite internet constellations.
