本文首先简述了SS-TDMA卫星通信系统的组成与工作原理,然后着重对该系统的按需分配时隙编排算法进行了讨论。在分析已有的时隙编排算法的基础上,提出了一个高效的时隙编排算法HEA(High-Efficient Time slot Assignment Algorithm)。它较之算法TSA-2,模式数平均减少了37.8％;而且它的运算复杂性为O(N~(4.5log_2N),从而较之运算复杂性为O(N~5)的算法TSA-2成倍地缩短了编排时间。
This article first briefly describes the composition and working principle of the SS-TDMA satellite communication system, and then focuses on the system’s on-demand slot scheduling algorithm is discussed. Based on the analysis of the existing time slot scheduling algorithm, an efficient time slot scheduling algorithm HEA (High-Efficient Time slot Assignment Algorithm) is proposed. Compared with algorithm TSA-2, the number of modes is reduced by 37.8% on average. Moreover, its computational complexity is O (N ~ 4.5log_2N), which is better than that of algorithm TSA-2 Exponentially shorten the scheduling time.
