【摘要】：高鐵的迅速發(fā)展為現(xiàn)有的高鐵無(wú)線通信系統(tǒng)帶來(lái)了一些新的挑戰(zhàn).一個(gè)準(zhǔn)確描述隧道信道特性的信道模型,對(duì)高鐵通信系統(tǒng)的設(shè)計(jì)和評(píng)估意義重大.由于隧道狹長(zhǎng)的空間、隧道本身的邊界性以及產(chǎn)生的波導(dǎo)效應(yīng)等,高鐵隧道中的信道特性不同于其他的高鐵場(chǎng)景.此外,隧道信道的一些特性目前還沒有被充分地研究.因此,考慮大尺度和小尺度衰落特性的準(zhǔn)確的隧道信道模型是十分必要和重要的.本文全面地綜述了已開展的隧道信道測(cè)量及采用不同方法建模的隧道信道模型,討論了未來(lái)高鐵隧道信道測(cè)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.
