提出了一种新的基于非合作博弈的动态频谱分配方案,考虑多个蜂窝用户服务中心和具有认知能力的设备到设备(D2D)通信用户组,利用伯川德(Bertrand)博弈理论来解决用户频谱分配问题,分别对D2D对用户组和蜂窝用户服务中心的效用函数进行了改进,并给出了蜂窝用户服务中心的最优定价和D2D对用户组的动态价格调整策略,进一步证明了纳什均衡解的存在性和算法的收敛性.通过仿真实验,分析了不同蜂窝用户数和学习因子对所提出方案性能的影响.与现有结果进行比较显示,新方案在频谱利用率和系统公平性方面均有改进.
A new dynamic spectrum allocation scheme based on noncooperative game is proposed. Considering multiple Cellular Subscriber Center and Cognitive Capability Device to Device (D2D) communication user groups, Bertrand game theory is used to solve the problem User spectrum allocation problem, respectively, D2D on the user group and the cellular user service center utility function has been improved, and given the optimal pricing of cellular user service center and D2D user group dynamic price adjustment strategy, further proof of Nash The existence of the equilibrium solution and the convergence of the algorithm.The impact of different number of cellular users and learning factors on the performance of the proposed scheme is analyzed by simulation experiments.Compared with the existing results, the new scheme has better performance in spectrum utilization and system fairness Aspects have improved.
