基于用频需求匹配度的频率指配算法

Spectrum Requirements Matching Degree-based Frequency Assignment Algorithm

针对大量异构用频装备同时同区域部署运用带来的频率资源紧张、指配效率低等问题,构建用频需求及频率资源表征模型,分析了频率资源指配流程,提出了基于用频需求匹配度的频率指配算法。该算法通过提高频率资源与用频需求带宽的匹配度,充分利用可用频率资源,实现资源集约使用。同时,为避免用频规律性被敌方识别、利用,引入频率间隔因子,提高了用频的灵活性、随机性。仿真结果验证了算法的有效性,相对于其他算法,可以显著提高装备用频需求满足度。

A large number of heterogeneous equipment deployed and applied in the same region and at the same time has brought about problems such as insufficient spectrum resource and low assignment efficiency.In response to above problems,spectrum requirement and resource characterization models are constructed,and frequency assignment process is analyzed.A frequency assignment algorithm based on the matching degree is proposed.By improving the matching degree between spectrum resources and signal bandwidths,the algorithm makes full use of available spectrum resources.At the same time,in order to avoid the regularity of frequency usage being identified and utilized by the enemy,a frequency interval factor is introduced to improve the flexibility and randomness of frequency usage.Simulation results verify the effectiveness of the algorithm:compared with other algorithms,it can significantly improve the satisfaction of spectrum requirements.
