摘要
首先分析了高铁无线环境的复杂性,介绍了FDD-LTE的技术特点。接着通过链路预算,选择合适的传播模型,最后计算出高铁场景的基站覆盖半径及考虑重叠区域后的基站站距。
The article first analyzes the complexity of high speed wireless environment, introduces the technology characteristics of FDD-LTE. Then through the link budget, it discusses about choosing suitable propagation models. Finally, it calculates the base station coverage radius in High-speed-railway＇s scene and distance between base stations considering the overlapping area.
