沙漠环境下的铁路无线通信系统信道特性研究

Research on Channel Characteristics of Railway Wireless Communication System in Desert Environment

选取穿过毛乌素沙漠的南端的太中银铁路,根据对于一些经典传播模型的研究,结合沙漠环境对无线电波的影响因素,对Okumura模型、Okumura-Hata模型、Egli模型和COST231-Walfish-Ikegami模型进行仿真分析,并与实际测量结果对比,最后对模型进行修正,得出最终适合于沙漠环境的铁路无线通信系统的传播模型。

This paper selects through the southern maowusu desert from Taiyuan to Yinchuan railway in China. According to research for some classical propagation model, combining desert environment on the influence factors ofradio waves ,the Okumura model ,Okumura Hata model,Egli model and COST231-Walfish-Ikegami model simulation analysis,and compared with the actual measurement results, finally to modify the model,the result is suitable for the propagation model of desert environment on railway wireless tern.
