Path Loss Models and Large Scale Fading Statistics for C-Band Train-to-Train Communication

Autor: Michael Walter, Ibrahim Rashdan, Paul Unterhuber, Thomas Kurner

The profound knowledge of wireless propagation is essential for wireless communication between vehicles. To evolve and test communication standards we need channel models in representative environments to neither over-, nor underestimate the effect o

In mobile positioning, it is very important to estimate correctly the delay between the transmitter and the receiver. When the receiver is in line-of-sight (LOS) condition with the transmitter, the computation of the mobile position in two dimensions

Influence of Railway Infrastructure on Train-to-Train Communications

Autor: Thomas Kurner, Michael Walter, Paul Unterhuber

The future of railway operation will rely on train-to-train (T2T) communications. Hence, we investigate the propagation mechanisms based on channel sounding measurements and derive channel models for T2T communications. For every wireless communicati
