地面空中接口在卫星移动通信的适用性研究

Research on applicability of terrestrial air interface in mobile satellite communications

为发展星地一体化网络、真正实现全球无缝覆盖,研究地面移动通信空中接口在卫星通信的适用性是一种有效的解决思路。本文系统性的介绍了地面3G/4G移动通信空中接口和卫星通信系统架构,总结了现有文献关于地面空中接口在星上的适用性初步评估,对比分析了各种地面空中接口在卫星信道环境下的链路性能,为地面空中接口在星上应用的改进方向提供了参考依据。

For the development of integrated satellite and terrestrial network andthe seamless global coverage, the research on the applicability of the terrestrial air interface in the satellite communications is an effective way. In this paper, we systematically describe the ground 3G/4G terrestrial air interfaces andthe satellite communications system architecture, summarize the existing study on the preliminary assessment of the applicability of terrestrial air interface in the satellite system, comparatively analyzethe link performance of different air interfaces in the satellitesystem, provide a reference to apply the terrestrial air interface in the satellite system.
