摘要
为精确分析具有线性视距(LOS)传输特性的5G毫米波自回传网络(mW-SBN)中阻塞问题的中断性能,提出了基于随机几何和随机形状理论的毫米波自回传网络中断分析方法。推导了毫米波宏基站(MBS)和微小区(SC)之间距离的统计特性,以及mW-SBN回传链路中断概率的闭型表达式,得出了mW-SBN网络参数与回传链路中断概率的关系式。仿真和计算结果表明:mW-SBN回传链路中断概率主要受MBS与SC之间距离及表征阻塞物大小和形状的参数等系统参数影响,仿真结果也印证了得出的理论分析。
In order to accurately analyze the outage performance of the blocking problem in 5 G millimeter wave self-backhaul network(mW-SBN)with line-of-sight transmission,a stochastic geometry and random shape theory based method for outage performance analysis is proposed.Firstly,the statistical characteristic of the distance between the millimeter wave macro base station(MBS)and the small cell(SC)is deduced.Then,the closed-form expression of the outage probability for mW-SBN backhaul link is derived.Finally,the relationship between the mW-SBN network parameters and the backhaul link outage probability is obtained.Simulation and calculation results show that the mW-SBN backhaul link outage probability is mainly affected by system parameters such as the distance between MBS and SC,and parameters which is used to characterize the size and shape of the obstacle and so on.The theoretical analysis is also confirmed by the simulation results.
