Localization of Scatterers in Railway Environments for Train-to-Train Propagation

Kurzfassung

Wireless communication became a key technology in the transportation domain. An increase of efficiency and safety can be achieved by connecting all traffic participants. In the railway domain wireless communication could enable new applications. In this contribution we focus on train-totrain (T2T) communication and investigate the Propagation conditions. In typical railway environments different types of objects along the track highly influence the propagation channel and, in turn, the performance of wireless T2T communications. Therefore, the characterization and modeling of the propagation effects are indispensable. In comparison to cellular or vehicle-tovehicle communication, T2T propagation is hardly investigated. In this paper we present how key parameters of the multipath components (MPCs) of the channel impulse response can be estimated. The estimation is based on measurement data. We estimate delay and Doppler of single-bounce MPCs and estimate the location of the corresponding scatterers.
