高速铁路高架桥场景中的复合无线信道特性

Composite Wireless Channel Characteristics for Communication Systems on Viaducts of High-Speed Railway

高架桥场景是高铁无线通信中的重要场景之一。针对该场景下的复合信道,基于瑞利信道模型和莱斯信道模型,对概率密度函数进行分析,推导出了两种新的概率密度函数。这不仅丰富了高铁高架桥场景下的无线信道理论,而且对未来高铁无线通信系统设计和优化有参考价值。

The viaduct scenario is one of the most important scenarios in the high-speed railway(HSR)wireless communications.For the composite channel in this scenario,the probability density function is analyzed based on the Rayleigh and Rician channel models,and two new probability density functions are derived.This can enrich the wireless channel modeling theories,and contribute to the design and optimization of wireless communication networks on HSR.
