At present, it adopts the method of “first come, first served, release after use” to provide a frequency guarantee for user communication. When multiple users access concurrently, there are problems of excessive consumption and the waste of frequency resources. In this paper, we propose the frequency resource planning of HF diversity communication network and model the optimization goal using the least frequency to meet the given user’s needs, and a genetic algorithm is used to solve the model. The simulation results show genetic algorithm has higher frequency utilization efficiency than the “first come, first served, release after use” method, which proves the necessity of frequency planning when the HF diversity network serves a large number of users.展开更多
