【摘要】：高铁的迅速发展为现有的高铁无线通信系统带来了一些新的挑战.一个准确描述隧道信道特性的信道模型,对高铁通信系统的设计和评估意义重大.由于隧道狭长的空间、隧道本身的边界性以及产生的波导效应等,高铁隧道中的信道特性不同于其他的高铁场景.此外,隧道信道的一些特性目前还没有被充分地研究.因此,考虑大尺度和小尺度衰落特性的准确的隧道信道模型是十分必要和重要的.本文全面地综述了已开展的隧道信道测量及采用不同方法建模的隧道信道模型,讨论了未来高铁隧道信道测量及建模的一些研究方向.
[Abstract]:The rapid development of high-speed railway has brought some new challenges to the existing wireless communication system. A channel model that accurately describes the channel characteristics of tunnels is of great significance to the design and evaluation of high-speed rail communication systems. Because of the narrow space, the boundary of the tunnel itself and the waveguide effect, the channel characteristics in the high-speed rail tunnel are different from other high-speed railway scenarios. In addition, some characteristics of tunnel channel have not been fully studied. Therefore, it is necessary and important to consider the accurate tunnel channel model with large scale and small scale fading characteristics. In this paper, the existing tunnel channel measurements and tunnel channel models based on different methods are summarized, and some research directions of tunnel channel measurement and modeling for high-speed rail are discussed.
