Using DVB-S2 adaptive coding and modulation for the provision of satellite triple play services

摘要

The outstanding spectrum efficiency of DVBS2 along with its adaptability and configurability makes it a very promising technology for next-generation satellite communications. This article discusses the application of the adaptive coding and modulation feature of DVB-S2 in the provision of satellite triple play services over an interactive DVB-S2/DVB-RCS network in order to compensate for fluctuations in propagation conditions. A cross-layer resource management system is proposed in order to adapt the system to such fluctuations and improve its overall efficiency. Based on areaspecific attenuation models, an efficiency study is presented, showing considerable capacity gains over static transmission schemes (DVB-S and DVB-S2 CCM).
