Abstract:
The ergodic capacity of device-to-device(D2D)communication underlaying cellular networks is analyzed. First, the D2D communication model is introduced and the interference during uplink period and downlink period is analyzed. In a D2D communication system, since it is very difficult to obtain the instantaneous channel state information(CSI), assume that only the transmitters know the statistical CSI and the channel coefficient follows an independent complex Gaussian distribution. Based on the assumptions, for the uplink period, the signal to interference plus noise ratio(SINR)of the D2D user equipments(DUEs)is expressed. Then the cumulative distribution function(CDF)and probability distribution function(PDF)formulae of the SINR of the DUEs are presented. Based on the SINR formulae during the uplink period, the ergodic capacity formula of the uplink period is derived. Subsequently, using the same methods, the ergodic capacity formula of the downlink period is derived. The simulation results show that the DUEs can still obtain a high ergodic capacity even in the case of a large number of DUEs. This result can be applied to the design and optimization of D2D communications.
针对蜂窝网络下D2D通信系统提出了一种遍历容量分析方法.首先, 对蜂窝网络下D2D通信模型进行了概述, 并分析了其上行时隙和下行时隙的干扰情况.在D2D通信系统中很难得到瞬时的信道状态信息, 故假设基站和终端仅知道统计的信道状态信息, 且信道系数服从独立复高斯分布.基于上述假设, 针对上行时隙得出DUE的信干噪比(SINR)表达式, 并基于该公式推导出DUE的SINR的概率分布函数和概率密度函数, 最终推导出DUE的上行遍历容量.利用相同方法, 推导出下行遍历容量.仿真结果表明, 即使存在较多DUE情况下仍然可以取得较高的遍历容量.研究结果可用于D2D通信系统的设计与优化.
