摘要
论文针对当前频谱资源紧缺、频谱使用效率不高的现状,通过对颜色敏感图论着色算法的分析,以最大化总带宽为频谱分配的最优化目标函数,采用协作式和非协作式两种方式,在最大系统公平准则下提出一种改进的频谱分配算法,在保证系统全局效益的同时,提高频谱分配的公平性。仿真结果表明,改进后算法较传统算法能有效改善频谱利用率,提高系统效益。
In this paper,the current shortage of spectrum,spectrum use efficiency is not high status of resources,through color sensitive graph coloring algorithm analysis to maximize total bandwidth spectrum allocation optimization objective function cooperative and non-cooperative in two ways,an improved algorithm for spectrum allocation system is improved at the maximum standards of fairness,to ensure system-wide benefits while improving the fairness of spectrum allocation.Simulation results show that the improved algorithm compared with the traditional algorithm can effectively improve the spectrum efficiency,improve system efficiency.
