Research on satellite beam hopping technology based on Digital Video Broadcast-Satellite Second Generation/Return Channel via Satellite

Satellite communication technology is rapidly developing towards the direction of high throughput and high flexibility as well as terminal miniaturization. DVB-S2/RCS standard as the second generation of satellite digital video broadcasting standard has been widely used and studied because of its outstanding performance advantages in system capacity and transmission capacity. The available spectrum resources in satellite communication system are increasingly short and the terminal traffic suddenly surge as well as satellite resource allocation is inflexible. Beam hopping technology as the latest communication technology in recent years has the advantages of dynamic resource allocation, improving service throughput and resisting strong directional interference. Combining DVB-S2/RCS and beam hopping technology and applying it to satellite communication system will greatly improve system throughput and provide richer interactive services. This paper mainly discusses DVB-S2/RCS standard, frame structure and frame structure design of beam hopping system. The combination of DVB-S2/RCS and beam hopping technology can improve the overall performance of communication system through simulation verification.
