| 摘要: |
| 为了提高认知无线电系统频谱分配的公平性,本文提出了采用两种协作式标准计算子图的认知无线电系统的频谱分配算法．首先对一些子图采用CMSB标准,频谱分配完之后,对其他一些子图采用 CMPF标准．系统仿真结果表明,系统公平性相比于原来的改进的算法有了明显的提高,同时本文算法的瓶颈认知用户信道容量得到了较大程度的改善． |

| Abstract: |
| To improve the system fairness of Spectrum Allocation on cognitive radio system, this paper presents a spectrum allocation algorithm of combining two standards on cognitive radio system. Firstly, some subgraphs allocate spectrum by using the Collaborative Max Sum Bandwidth (CMSB) standard, after finishing spectrum allocation, then other subgraphs adopt Collaborative Max Proportional Fair (CMPF) standards. Compared with the previous improved parallel algorithm, the simulation shows that the system fairness has been improved obviously, at the same time, the channel capacities of bottleneck cognitive users have been improved greatly. |
