摘要
针对设备到设备(device to device, D2D)直连技术复用蜂窝网络资源导致用户间干扰的问题,提出了一种基于K-means与Gale-Shapley稳定匹配算法的D2D通信干扰管理资源分配方案。通过分析信号与干扰加噪声比公式,采用K-means聚类算法进行用户分组,降低用户间干扰,实现多对一资源复用;为提高通信系统容量且保证用户的公平性,采用Gale-Shapley稳定匹配算法在用户分组基础上实现信道资源共享。仿真结果表明,与基于贪婪的图着色资源分配算法相比,本文算法在保证系统容量基本稳定的情况下,系统干扰降低了10%~30%。
In this paper,we propose a resource allocation scheme for managing interference in device to device(D2D)communication,aiming to address the issue of inter-user interference caused by the multiplexing of cellular network resources.The proposed scheme is based on K-means and Gale-Shapley stable matching algorithm.By analyzing the signal to interference plus noise ratio(SINR)formula,K-means clustering algorithm is used to group users,reduce the interference between users,and achieve multiple to one resource reuse.To improve communication system capacity and ensure fairness among users,Gale-Shapley stable matching algorithm is used to realize channel resource sharing within the user groups.Simulation results show that the system interference is reduced by 10%to 30%compared to the greedy graphical coloring resource allocation algorithm,while maintaining stable system capacity.
