【摘要】 针对多复用模式下D2D用户的功率分配问题,本文提出一种基于博弈论的D2D功率分配算法。在保证各用户都能正常工作的前提下,对蜂窝用户和D2D用户同时进行功率分配,建立博弈模型,引入代价函数改进博弈模型的效用函数,最终求得系统模型的纳什均衡解。通过仿真验证了本文提出的算法能有效控制系统内干扰,同时提高系统吞吐量。更多还原

【Abstract】 Aiming at the power allocation problem of D2D users in multi-reused mode,a D2D power allocation algorithm based on game theory was proposed in this paper.On the premise of ensuring that all users can work normally,the power allocation of cellular users and D2D users was carried out simultaneously,the game model has been established,the utility function of the game model was improved by introducing the cost function,and the Nash equilibrium solution of the system model was finally obtained.Simulation results showed that the proposed algorithm can effectively control the interference and improve the system throughput.更多还原
