摘　　要：针对当前大多数无中心多频时分多址(Multi Frequency Time Division Multiple Access,MF-TDMA)卫星通信系统资源分配中资源利用率低、业务匹配率低的问题,提出了一种无中心MF-TDMA卫星通信系统的帧结构及其组网和资源按需分配方法,并通过仿真分析将其与传统资源调控算法进行比较。无中心MF-TDMA资源按需分配算法通过提高时隙资源的利用率,相比传统资源调控算法在业务匹配度、业务呼通率等参数上有明显改善。仿真结果表明,所提的资源按需分配算法能够更大程度满足动态变化的卫星通信业务的需要。To address the problems of low resource utilization rate and low service matching rate in the resource allocation of most of the current centerless MF-TDMA(Multi-Frequency Time Division Multiple Access)satellite communication systems,this paper proposes a frame structure of a centerless MF-TDMA satellite communication system and its networking and resource on-demand allocation method,and compares it with the conventional resource control algorithms through simulation analysis.Compared with conventional resource control algorithms,the centerless MF-TDMA resource on-demand allocation algorithm shows significant improvement in parameters such as service matching degree and service call-through rate by improving the utilization rate of time slot resources.Simulation results indicate that the proposed resource on-demand allocation algorithm can meet the needs of dynamically changing satellite communication services to a greater extent.
