摘　　要：针对现有短波无线接入网的固定式频谱分配方法难以满足使用智能跳频技术新要求的问题,分析智能跳频短波无线接入网的通信需求,提出智能跳频短波无线接入网的动态频谱分配策略及算法。首先将各机动用户和接入基站看作一子网;然后将对各子网的频谱分配建模为基于图着色理论的智能跳频短波无线接入网频谱分配模型;最后结合通信需求提出分配策略和算法,完成频谱分配并进行了仿真分析。结果表明,这些频谱分配策略及算法以不同的目标进行频谱分配,能够有效支撑智能跳频技术在短波无线接入网中的应用,与固定式频谱分配方法的定频通信相比,在网络效益、子网满意度、网络公平性、网络支持用户数和频谱利用率等方面均有明显提升,同时能有效降低互扰率。Because of the problem that the existing fixed spectrum allocation method of HF radio access to network cannot satisfy the new requirement of intelligent frequency hopping technology, the communication demand of HF radio access to network based on intelligent frequency hopping was analyzed, and the strategy and algorithm of dynamic spectrum allocation in intelligent frequency hopping HF radio access to network were proposed. Firstly, mobile users and base stations were regarded as a subnet, then the subnet of spectrum allocation model was modeled as spectrum allocation model by using graph coloring theory. Finally, allocation strategy and algorithm were put forward combined with communication demand to complete spectrum allocation. Simulation results show that the proposed strategy and algorithm can effectively solve application problem of intelligent frequency hopping technology in HF radio access to network. Compared with fixed frequency communication of fixed spectrum allocation method, dynamic spectrum allocation can obviously increase network benefits, subnet satisfaction, network fairness, the number of users and spectrum efficiency, and reduce the mutual interference ratio at the same time.
