Abstract This paper provides an overview of broadband satellite communication networks based on Digital Video Broadcasting-Return Channel System (DVB-RCS) standard, with an emphasis on the dynamic allocation of multi-access channel. A novel combined Demand Assignment Multiple Access (DAMA) scheme is proposed, in which chaotic prediction method is employed for self-similar traffic. For comparing the performance of different schemes, OPNET software is used to build a simulation system. Simulation results indicate that the novel scheme has better performance under heavy channel load and when the traffic has high degree of self-similarity.
