Analysis of channel correlation characteristics in GEO mobile satellite communications

Channel prediction is the premise for the application of adaptive transmission in mobile satellite communications with long propagation delay. Particularly, in GEO mobile satellite communication systems, the satellite channel correlation characteristics are analyzed for the mobile terminals at different positions and along different directions, and the predictability of the satellite channel is discussed associated with the channel correlation results. The foundation for the application of adaptive transmission in GEO mobile satellite communications is established accordingly.
