Joint Congestion Control and Scheduling Algorithm in a Multi-Access and Multi-Service Satellite System

The work proposes a solution to the bandwidth allocation problem in a multi-user satellite telecommunications system, aiming to an efficient radio resource exploitation. This task is performed sharing dynamically, each signalling time, the resources available among the requiring users services, avoiding congestion states and guaranteeing an agreed Quality of Service. The proposed algorithm is fully compliant with the DVB-RCS standard, but due to its independence from the network technology it can be easily adopted in CDMA systems.
