【摘要】:为了提高蜂窝式卫星移动通信的通信质量和频谱使用效率,必须对各波束载波频率的选取进行合理规划.为此,将频谱资源动态规划问题形式化,提出一种基于遗传算法和启发式搜索的频谱动态规划算法,综合考虑同频复用距离、波束分组类约束、动态变化的可用频谱资源、用户业务频谱需求等,动态地将可用频谱资源分配至各波束,以最大效用地利用卫星频谱资源.
[Abstract]:In order to improve the communication quality and spectrum efficiency of cellular satellite mobile communication, it is necessary to plan the carrier frequency of each beam reasonably. In this paper, a spectrum dynamic programming algorithm based on genetic algorithm and heuristic search is proposed to formalize the problem of spectrum resource dynamic planning, which considers the frequency multiplexing distance, the constraint of beam grouping class and the dynamic change of available spectrum resources. The available spectrum resources are dynamically allocated to each beam to maximize the utility of satellite spectrum resources.
