Research on Adaptive Communication Method of Inter-satellite Link in Satellite Group System

The article conducts research on adaptive communication processing method of inter-satellite link in satellite group system. The purpose of this study is to realize the research of communication technology under the condition of dynamic change of inter-satellite distance by constructing the architecture of adaptive coding and modulation system, and to provide theoretical and technical support for establishment of inter-satellite intelligence communication system. The research contents include the construction of adaptive coding and modulating system architecture, the establishment of inter-satellite communication knowledge base and the construction of simulation verification platform. This paper focuses on the inter-satellite autonomous intelligent adaptive coding and modulating technology. By studying the dynamic change of channel environment, a dynamic data transmission mechanism based on adaptive coding and modulating is proposed, which realizes efficient transmission under different link quality. The key technologies include adaptive coding technology, adaptive modulation technology and adaptive coding modulation engine design technology. This study is of great significance to improve the theoretical method and technology of adaptive communication processing of inter-satellite link in satellite group system, and also provides reference for wireless communication in other dynamic and complex environments.
