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

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 area-specific attenuation models, an efficiency study is presented, showing considerable capacity gains over static transmission schemes (DVB-S and DVB-S2 CCM).
