面向5G-R高铁站场景的CDL建模与研究
CDL modeling and research for 5G-R high-speed railway station scenario
摘要
Abstract
To promote the application of fifth-generation mobile communication technology(5G)in the construction of high-speed rail dedicated networks,this paper takes the Xiamenbei Railway Station in the 2.1 GHz frequency band as the research scenario,studying the significant multipath spatial characteristics brought about by objects such as columns,tracks,and platforms in the scenario.Through Ray Tracing(RT)simulation,multidimensional multipath data from the transmitter to the receiver in the high-speed railway station scenario is obtained;based on the K-means clustering algorithm,the multipath signals are clustered,and relevant cluster parameters are extracted and analyzed to complete the construction of the Cluster Delay Line(CDL)model for the high-speed railway station scenario.This provides spatial domain information of multipath for different polarization combinations of transmitters and receivers in the high-speed railway station scenario,complementing the channel model of high-speed railway station scenario for 5G-Railway(5G-R),and serving the construction of dedicated mobile communication systems for railways using 5G.关键词
