| 摘要: |
| 为了解决多主用户和多次级用户共存网络的频谱资源分配问题，提出了一种基于斯塔科尔伯格（Stackelberg）博弈的动态频谱接入控制算法。该算法通过三阶段Stackelberg博弈模拟主用户频谱竞价，博弈过程中次级用户以最大化传输速率为目的接入主用户频谱，同时设计了一种迭代过程来求解纳什均衡。实验计算与结果分析证明了纳什均衡唯一存在性的充要条件，并说明了迭代过程的收敛性以及主用户最佳效用的影响因素。 |

| Abstract: |
| In order to realize the spectrum resource allocation of coexistence networks between primary users and secondary users,a dynamic spectrum access control algorithm based on Stackelberg game is proposed.The algorithm simulates the primary users spectrum bidding through the three-stage Stackelberg game.The secondary users access the primary spectrum to maximize transmission rate,and a fast iterative process is designed to solve the Nash equilibrium.Experimental calculation and performance analysis show that the necessary and sufficient conditions of Nash equilibrium can be proved,and the convergence of the iterative process and the factors of the primary user best utility can be explained. |
