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
