| 摘 要： | 以拟建合湛高速铁路经过遂溪机场的线路方案为例,对Longley-Rice不规则地形信道模型进行了简要介绍,仿真分析了该模型在不同传输距离和置信区间下信号的衰落情况。现场实测数据验证了Longley-Rice信道模型的准确性和合理性。结合仿真和实测结果,提出了GSM-R无线覆盖的解决方案,并且为铁路选线方案的优化提供了技术支撑。

| Abstract: | In the route plan of Hepu-Zhanjiang high-speed railway through Suixi airport,the irregular Longley-rice terrain channel model is briefly introduced and the signal fading of the model over different transmission distances and confidence intervals is analyzed via simulation.The accuracy and rationality of Longley-rice channel model are verified by field test data.Combined with the simulation results and field test results,a GSM-R wireless coverage solution is proposed,providing a technical support for the optimization of railway route selection scheme. |
