中文摘要	沙漠中的沙尘暴或风沙天气对无线通信有重要的影响,随着我国越来越多的高速铁路沙漠中建成,研究在沙尘暴、沙尘天气下GSM-R通信系统的传播模型对于保证GSM-R通信的安全和稳定有十分重要的意义。本文结合太原-中卫-银川铁路毛乌素沙漠南端定边至银川区段GSM-R通信系统,对沙漠环境沙尘粒子的散射产生的路径损耗进行了分析,将传统路径损耗模型与实际测量数据进行了误差研究,对路径损耗模型的参数因子进行了调整和优化,通过仿真实验与结果的分析,证明该改进模型能更加逼近实际测量数据。
英文摘要	Sand storms and windy & dusty weather in desert areas have important influence on wireless communication. As more and more high-speed railway lines have been built in desert areas in our country, research on the GSM-R propagation model of communication systems in the sand storm and windy & dusty climate has very vital significance to ensure the safety and stability of railway communication systems. In this paper, with refernce the GSM-R communication system of the Dingbian-Yinchuan section of the Taiyuan-Zhongwei-yinchuan Railway located at the south end of the Maowusu Desert, the path losses generated due to scattering of dust & sand particles were analyzed, errors were studied in comparison between the traditional path loss model and actual measured data, and the error parameters factor of the path loss model was adjusted and optimized. The simulation experiments and results prove that the improved pass loss model is more approximate to the actual measured data.
