| 摘要: |
| 针对多个新建航空无线电导航台站高效频率指配问题，根据美国联邦航空管理局（FAA）的频谱管理规范，研究了在已有多台站场景下的频率指配算法。总结了导航台站频率指配的复用干扰和频率配对两个约束条件，给出了提高频谱利用率的频率指配度量准则，设计了单个新建台站的频率指配算法，给出了多台站频率指配的深度优先递归搜索算法。数值仿真结果表明，所提算法在为多个新建台站同时指配频率时，可有效提高频谱利用率。 |

| Abstract: |
| In order to efficiently allocate spectrum resource for aeronautical navigational aid(NAVAID) facilities under the scenario with many stations,spectrum allocation algorithms are proposed based on the spectrum management regulation of Federal Aviation Administration(FAA).With the constraints of frequency reuse interference and frequency pairing,a spectrum efficiency oriented metric is first proposed,and on this base,a spectrum allocation algorithm is provided for the case of a single-station. Then,a depth-first searching based spectrum allocation method is further proposed for the case of multi-stations. Numerical simulation results show that the proposed spectrum allocation algorithms can assign frequencies for all applied stations with high spectrum utilization. |
