Abstract: Regarding to the limited and costly resources, multi-frequency time-division multiple access (MF-TDMA) technique is widely applied to the uplink of broadband communication satellites. The time slot allocation strategy is the key to guarantee the efficient utilization of the system resources. A novel satellite slot allocation based on priority function was proposed, and efficiently improved the performance of resource utilization. The time delay and channel utilization of the algorithm can be validated through the simulation for different types of traffic. The performance of classical schemes was compared. The theoretical analysis and simulation results show that new algorithm can efficiently improve channel utilization in satellite resource allocation, especially when the number of satellite terminals is large. The algorithm is simple and easy to implement in satellite communication system.
