Abstract:

In this paper, we consider broadband satellite systems using MF-TDMA (Multi-Frequency Time Division Multiple Access) scheme. First, we analyze return link, superframe structure, superframe structure, and QoS (Quality of Service) parameters in broadband satellite systems, and mathematically formulate the QoS-based optimal timeslot allocation problem as a nonlinear integer programming problem for broadband satellite systems with clear-sky and rain-fade satellite terminals, and multiple data classes. Next, we modify the proposed problem to solve it within in a fast time, and suggest the QoS-based optimal timeslot allocation scheme. Extensive simulation results show that the proposed scheme finds an optimal solution or a near optimal solution within 5 ms at Pentium IV PC.
