空天智能超表面辅助通信技术综述
A Survey on Aerial and Space Intelligent Metasurface-Assisted Communication Technologies
摘要
Abstract
Addressing the challenges of severe high-frequency signal attenuation and costly deployment in sixth-generation space-air-ground integrated networks,the integration of reconfigurable intelligent surface(RIS)technology with aerial and space platforms represents a promising research paradigm.This paper systematically surveys aerial and space RIS-assisted communication technologies.First,two typical deployment scenarios are presented:RIS mounted on aerial platforms such as unmanned aerial vehicles and high-altitude platforms,and on space-based platforms such as satellites,highlighting their distinctive advantages in flexible deployment and wide-area coverage.Second,key technological advances are comprehensively analyzed across three dimensions:beamforming techniques,channel estimation methods,and performance analysis frameworks.Third,two critical challenges toward practical deployment are examined:hardware constraints and system design complexities.Finally,conclusions are drawn with an outlook on future research directions.关键词
