Abstract:Summary
To address the problem that Ka‐band satellite communication signal transmission is easily affected by rainfall and terminal environment, combining the characteristics of high‐speed movement of LEO satellites and the wave propagation characteristics of satellite‐ground links, this paper establishes a Markov synthesis model of four‐state satellite channels based on Ka‐band that integrates rainfall attenuation and terminal shadow attenuation, and a scheme for adaptive coding and modulation selection based… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
