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.

关键词: 卫星频谱规划, 遗传算法, 启发式搜索

Abstract: Appropriate carrier frequency allocating for satellite spot beams is necessary for improving the qaulity of service (QoS) and spectrum utilization efficiency of cellular satellite mobile communication systems. This paper formalizes the problem of dynamic carrier frequency allocating and then proposes a dynamic spectrum planning algorithm based on genetic algorithm(GA) and Heuristic Search, which comprehensively considers the frequency reuse distance, beam group constraint, varying spectrum resource available, and spectrum requirement of a spot beam, to utilize the spectrum resource as efficient as possible.

Key words: satellite spectrum planning, genetic algorithm, heuristic search
