| 摘 要： | 城市轨道交通特殊场景下对LTE-M(城市轨道交通车地综合通信系统)系统性能进行准确评估是一个非常复杂的问题。提出了基于射线追踪技术的LTE-M系统性能仿真方法。该方法无需进行信道测量,通过海量计算即可得到无线信道特性参量,进而进行性能仿真,特别适合城市轨道交通等缺少标准信道模型的场景。

| Abstract: | It is complicated to evaluate the performance of LTE-M system accurately in the particular scenario of urban rail transit.An LTE-M system performance emulation approach based on ray-tracing technology is proposed.The approach can obtain the channel characteristic parameters by massive computing without channel measurement to conduct the system simulation,which is particularly suitable for scenarios lack of standard channel models such as urban rail transit. |
