摘要
频谱资源紧缺背景下,设备到设备通信是有效的频率复用方法.利用随机几何工具,在复合信道条件下,对以网络为中心分簇中用户通信模式的选择及性能分析展开研究.考虑以网络为中心分簇的网络模型,根据用户与最近基站、最近用户之间的距离比确定用户的通信模式,在分析用户通信模式选择概率的过程中充分考虑了基站和用户空间位置的随机性.最后,推导了典型用户的平均数据速率表达式,并分析了基站与用户之间的相对位置、协作簇内基站数目、用户数目以及阴影效应的影响.
Abstract
Under the background of shortage of spectrum resources,device-to-device communica-tion is an effective frequency multiplexing method.In this paper,the stochastic geometry tool is used to study the selection and performance analysis of the user communication mode in network-centric clustering under the composite fading channel.Considering the network-centric clustering model,the user communication mode is determined by the ratio of the distance between the user and the nearest base station to the distance between the user and the nearest user.Finally,the average data rate expression of a typical user is derived,and the effect of relative position between base sta-tions and users,the number of base stations in the cooperative cluster,the number of users and the influence of shadow are analyzed.
