• Broadband satellite communications
• Nonnegative matrix factorization
• Traffic prediction

Multi-user traffic prediction is an important issue in broadband satellite communications system. In view of multiple UTs (User Terminal) which are treated by a single ST (Satellite Terminal), a novel NMF-based (Nonnegative Matrix Factorization-based) multi-user traffic prediction method is proposed. Compared with previous prediction schemes, the new method can reduce computational complexity and remain comparable prediction accuracy. Simulation results based on real traffic data testify the validity of the proposed method.
