Résumé / Abstract
This paper reports an evaluation of UWB radio technology and Time Reversal (TR) technique in tunnel environment for train to- wayside communication. UWB technology has the potential to offer simultaneous ground-to-train communication, train location and obstacle detection in front of the trains. Time Reversal channel pre-filtering facilitates signal detection and helps reducing interference. Thus, UWB-TR combination provides a challenging, economically sensible, as well as technically effective alternative solution to existing signalling technologies used in urban transport systems. This paper focuses on the communication function and reports simulation performance evaluation of such combinations in a deterministic tunnel channel model.
