| Abstract: | Timeslots assignment can have a great impact on the bandwidth allocation efficiency in multi-frequency time division multiple access (MF-TDMA) satellite system. In this paper a multiple frequency channels reserved timeslots assignment algorithm is proposed for MF-TDMA user terminals (UTs) with real-time traffic. The scheme can reserve several frequency channels simultaneously for one UT and realize fast timeslots block searching within a MF-TDMA frame. Computational complexity analysis demonstrates the performance of the proposed method on computational efficiency. What’s more, simulation results show that both channel utility and connection rejection ratio can be improved compared with existing algorithm. |
