| 摘要: |
| 本文从认知无线电系统实际应用出发,首先应用图论算法快速的预分配频谱,同时为再次分配提供了公平性,然后用博弈论思想对初次分配的信道优化,完成认知用户之间的频谱再次分配．最后仿真表明频谱的资源可以充分利用,在传输功率的约束下,每个认知用户提高自身的速率,合理地分配功率,证明了本文图论和博弈论联合的算法的有效性． |

| Abstract: |
| Considering practical application in cognitive radio system, a graph theory algorithm is applied firstly to rapidly allocate spectrums (channels), which provides distribution fairness, and then the game theory algorithm is used to optimize first distribution spectrums (channels) and complete spectrum redistribution between cognitive users. Finally, simulation results show that the spectrum resources can be fully utilized, and under power transmission constraints, each cognitive user optimizes its own utility (rate) and distributes reasonably power. The simulation verifies that joint algorithm based on graph theory algorithm and game theory algorithm is effective. |
