摘　　要：如何高效利用有限的信道资源是MF-TDMA卫星通信系统的关键技术之一。分析了预规划载波的固定配置信道的方法。为了提高载波能力和业务需求的匹配性,提出了一种随业务变化动态调整信道载波算法,根据系统的实际业务需求,对业务申请信息进行数据分析和分类统计,判定对当前信道内的载波的调整方向,实时动态调整信道的载波速率和数量,保证信道容量和业务需求的一致性。仿真结果表明,这一动态调整方法能够保证信道能力和业务需求的一致。How to efficiently utilize the limited channel resources is one of the key technologies of MF-TDMA satPunicationsystem. The method of fixed configuration by preplanning channel carrier is analyzed. To improve the matching between the carrier capability and traffic requirement, this paper proposes an algorithm that dynamically adjusts the channel carrier along with traffic variation. The algorithm performs data analysis and classification of traffic request information,determines the adjusting direction of the current channel carrier,and adjusts the carrier rate and quantity in real time to ensure the consistency between the channel capacity and traffic requirement. The simulation results show that this dynamic adjusting method can guarantee the consistency of channel capability and traffic requirement.
