摘　　要：文中利用抛物方程(parabolic equation,PE)方法,从纵向剖面和区域覆盖两个维度,对3.6 GHz频点在都市、郊区、乡村三种典型场景下的传播特性进行分析,并将仿真结果与ITU-R P.1546方法仿真结果进行对比分析.分析结果表明:PE方法能够描述信号传输直射、绕射、反射波束,与各场景传播特点相匹配,具有较好的适用性;PE方法与ITU-R P.1546方法变化趋势有着较好的一致性;PE方法结合地形的不规则变化,覆盖仿真结果更为细致,体现出“确定性预测”的优势.本文研究成果可为5G毫米波典型应用场景传播特性预测提供支撑,对5G通信系统设备部署及网络布局具有重要的工程意义.In order to analyze the propagation characteristics of 3.6 GHz signal in urban,suburban and rural areas,the parabolic equation(PE)method is used to simulate the longitudinal profile and regional coverage propagation characteristics.The simulation results are compared with those of the ITU-R P.1546 method.The analysis results show that:the PE method can describe the direct,diffractive and reflected beam of signal transmission,which matches the characteristics in various scenes;the PE method has a good consistency with the variation trend of ITU-R P.1546 method.The coverage simulation results are detailed descripted with irregular terrain changes,which reflecting the advantage of“deterministic prediction”.It is expected that this paper can be further expanded for potentially providing a basis support for the prediction of propagation characteristics in typical scenarios and have efficient engineering significance for the deployment of 5G communication system.
