【摘要】：针对目前端对端(D2D)通信资源共享算法无法解决资源利用率和信道干扰之间矛盾的问题,为了改善D2D通信性能,设计一种基于博弈论的D2D通信资源共享算法.该算法将通信系统吞吐量作为目标,通过引入博弈论实现各用户间的通信资源共享,使通信链路之间合理地分配资源,减少信道之间的干扰,提高蜂窝链路的通信质量.与经典D2D通信资源共享算法进行对比实验结果表明,该算法明显提高了D2D通信质量,提升了信道利用率,系统总吞吐量得到大幅度提高.
[Abstract]:In order to improve the performance of D2D communication, the current end-to-end D2D communication resource sharing algorithm can not solve the contradiction between resource utilization and channel interference. A D2D communication resource sharing algorithm based on game theory is designed, which takes the throughput of communication system as the target and realizes the communication resource sharing among users by introducing game theory. It makes the communication link allocate resources reasonably, reduce the interference between channels, and improve the communication quality of the cellular link. The experimental results show that compared with the classical D2D communication resource sharing algorithm. The algorithm improves the quality of D2D communication, improves the channel utilization, and improves the total throughput of the system.
