Abstract: Satellite communication networks are evolving to become an integral part of terrestrial networks. With this integration comes the promise of wireless services to remote underserved areas and also backup connectivity in the presence of network failures or disaster events. We discuss broad trends that are changing the design of satellite communication networks fundamentally.  Specifically, signal processing advances will be addressed with focus on multi-antenna transmit precoding techniques to improve coverage and spectral/energy efficiency, as well as link reliability and security. Recent advances on symbol-level precoding, including experimental validation in satellite systems will be presented.
