Implementation of Spreading Techniques in Mobile DVB-S2/DVB-RCS systems

In this paper we address the emerging application of mobility to DVB-S2/DVB-RCS systems, sometimes also referred to as Satellite-On-The Move (SOTM) communications. Satellite communications have great commercial success in digital audio and video broadcasting as they exploit the inherent wide area coverage for distribution content. It was a natural consequence to extend its use to multimedia applications; DVB-S2/DVBRCS standards offer a commercially proven solution for fixed terminals in that sense. This paper presents techniques of spectrum spreading for DVB-S2/DVB-RCS systems detailing which solutions were envisaged and presenting some performance results.
