摘要

在郑西高铁两种高架桥场景下，以300 km/h的速度进行930.2 MHz窄带测量。测量数据的一阶和二阶统计量，如水平交叉率(LCR)和平均衰落持续时间(AFD)，与Rayleigh、Rice和Nakagami模型的理论值进行了比较。在轨道交通控制与安全国家重点实验室，利用prosim c8无线信道仿真器建立了仿真系统。根据仿真结果，提出了两种基于WINNER II D2a通道模型的高架桥场景下的新模型。

Analysis and emulation of the small-scale fading characteristics in the high-speed rail scenarios

Narrow band measurements at 930.2 MHz are carried out in two kinds of viaduct scenarios on the Zhengzhou-Xi'an high-speed railway at the speed of 300 km/h. The first-order and second-order statistics of the measured data, such as level crossing rate (LCR) and average fade duration (AFD), are compared with theoretical values of Rayleigh, Rice and Nakagami models. An emulation system is set up in the State Key Lab of Rail Traffic Control and Safety using a Propsim C8Radio Channel Emulator. Two new models based on WINNER II D2a channel model are proposed for viaduct scenarios according to the emulation results.
