| 摘 要： | 在认知无线电系统中,博弈论算法从频谱共享池中获取频谱困难.为了提高自身传输速率,同时使频谱可以充分利用,采用图论算法快速地初次分配频谱,联合博弈论方法优化信道.仿真结果表明:在传输功率的约束下,联合频谱分配算法提高了自身的效用(速率),能够充分利用频谱资源,合理分配功率,仿真验证了图论和博弈论联合的算法是有效的. |

| Abstract: | In order to improve transmission rate, and make full use of spectrum resources, the graph theory algorithm was applied firstly to allocate rapidly spectrums (channels), and then the channels were optimized by game theory algorithm. Simulation results showed that the spectrum resources could be fully utilized. Under power transmission constraints, the utility (rate) of cognitive users is improved by using joint spectrum allocation algorithm, and the power is distributed reasonably. The simulation verified that joint algorithm based on graph theory and game theory is effective. |
| Keywords: | graph theory game theory first spectrum distribution second distribution cognitive radio |
