The profound knowledge of radio wave propagation is essential for the design and test of wireless communication systems especially in demanding environments and for mobile transmitters and receivers. In this article we provide an accurate description of the relevant propagation parameters for train-to-train scenarios considering typical environments such as railway stations, open field and hilly terrain with cutting. At the beginning of this contribution we shortly describe the comprehensive train-to-train measurement campaign which is the basis for all further evaluations. We treat the stationarity of the channel in time and frequency and derive power delay profiles, and the Doppler spectral densities. Furthermore, distance-variant statistics about the $k$
-factor, delay spread and Doppler frequency spread are presented. We show that these parameters change very much for different environments and distances. For all stochastic channel parameters we propose distance dependent model parameters.

列车到列车通信的随机信道参数
无线电波传播的渊博知识对于无线通信系统的设计和测试至关重要,尤其是在苛刻的环境中以及移动发射器和接收器中。在本文中,我们提供了列车到列车场景的相关传播参数的准确描述,考虑了典型环境,例如火车站、开阔的田野和带切割的丘陵地形。在这篇文章的开头,我们简要描述了全面的列车到列车测量活动,这是所有进一步评估的基础。我们在时间和频率上处理信道的平稳性并推导出功率延迟分布和多普勒频谱密度。此外,关于 $千$
-因子、延迟扩展和多普勒频率扩展。我们表明这些参数对于不同的环境和距离会有很大的变化。对于所有随机通道参数,我们建议距离相关模型参数。
