Learning Outcomes
The aim of the course is to introduce the postgraduate student in satellite communications emphasizing on subsystems, techniques and applications. The existing background in communication systems and antenna issues is enriched specializing in fields like radiolink theory, communication techniques, coding, multiple access, networks and Tx/Rx systems. Also, among the aims of the course is a state of the art update on key emerging technologies and applications as well as on future systems and innovative research areas.
General Competences
  • Apply knowledge in practice
  • Retrieve, analyse and synthesise data and information, with the use of necessary technologies
  • Adapt to new situations
  • Work autonomously
  • Advance free, creative and causative thinking
