摘　　要：针对目前频谱资源紧缺的现状,通过对图论着色模型的分析理解,提出了一种基于用户公平性的改进颜色敏感度的图论着色算法,该算法从用户的网络效益和使用频谱数出发,引入公平因子,改变频谱分配过程中给用户的分配优先级,保证频谱分配的公平性。通过仿真表明其可行性。Aiming at the present situation of spectrum resources, an improved spectrum allocation algorithm is proposed, which is a modification of CSGC（Color Sensitive Graph Coloring） algorithm based on proportional fairness. A fair factor of users＇ network efficiency and channel quantity is introduced based on traditional labeling system. The simulation results show that the algorithm is feasible.
