Study on HF Frequency Assignment Problem Based on Genetic and Simulated Annealing Algorithm

针对短波chirp选频系统的通信网络频率分配问题,建立了合理的干扰模型。同时利用系统所提供的参数,设计了新的算法参数。仿真结果表明,该算法在干扰约束条件下,算法能使全网通信质量达到最优,并对参数选择操作进行比较,给出了就如何设置算法运行参数的合理建议。

A reasonable interference model is built in allusion to the frequency assignment problem of communication networks in the HF chirp -sound- ing system. And new algorithm parameters are designed by employing the measuring parameters provided by the system. The simulation results indicate that the modified algorithm can achieve the global optimization of communication quality for whole HF networks when the interference is restricted. Some useful suggestions on how to set parameters of the algorithm are proposed according to comparing results of the parameter selection operation.
