面向5G的D2D资源优化算法研究

Research on 5G oriented D2D resource optimization algorithm

科技的迅猛发展和智能化设备的不断涌现使得频谱资源的匮乏更加明显,不断推进5G的研发和投产成为了当前通信行业的大趋势之一。为了解决无线网络用户增多带来的用户间互相干扰大及传输速率低等问题,文中从D2D通信模型的介绍入手,首先对D2D通信中的资源共享模式进行了详细介绍,然后分别对MIMO系统模型和MIMO—D2D系统模型进行了介绍,最后在对网络资源分配方案优化设计的基础上,研究了基于最大SLNR准则的网络资源优化算法。

With the rapid development of science and technology, the emergence of intelligent equipment makes the shortage of spectrum resources more obvious. Continuously promoting 5G technology has become one of the major trends in the current communications industry. In order to solve the problems of large mutual interference and low transmission rate caused by the increase of wireless network users,this paper starts with the introduction of D2 D communication model. Firstly,the mode of resource sharing in D2 D communication is introduced in detail; Secondly,the MIMO system model and MIMO-D2 D system model are introduced respectively; Finally,based on the optimization design of network resource allocation scheme,the network resource optimization algorithm based on maximum SLNR criterion is studied.
