摘　　要：针对传统基于图论着色原理的频谱分配算法公平性较差问题进行研究,提出一种在最大效益准则下基于分配公平性改进的CSGC频谱分配算法。该算法在最大化系统效益准则下,充分考虑了用户对频谱资源占用因素,改进了原有CSGC算法。尤其是在频谱资源紧张情况下,保证了分配的公平性,保障了弱势用户的需求。MATLAB仿真实验结果表明,该算法在保障系统效益牺牲不大的前提下,提高了频谱资源分配公平性。For the problem of that the worse fairness of the allocation algorithm based on the traditional graph coloring, proposed a CSGC improved algorithm. Under the principIe of Max-Sum-Reward, this algorithm improves the traditional CSGC algorithm by considering the factor of spectrum utilization. Especially in the cases of limited spectrum resource, this algorithm ensures the fairness of allocation and the needs of vulnerable users. The simulation results show that under the premise of system＇s reward this algorithm improves the overall fairness of the system.
