OneWeb低轨星座信号结构解析与思考
Signal Structure Analysis and Thought of OneWeb LEO Constellation
摘要
Abstract
As a supplement to terrestrial mobile communication networks,low earth orbit(LEO)satellite Internet has become an impor-tant 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 com-munication 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 One-Web 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.关键词
