ISE C19- Wireless Communications for Railways

Researchers: Mats Bengtsson (Project manager), Leandro Lopez (PhD student)

Source of Funding: Trafikverket (Swedish Transport Administration)/ S2R

The project contributes to the work on adaptable communications for railways within Shift2Rail, where
Trafikverket is the Swedish partner in Shift2Rail using KTH based researchers as linked third parties. In the
project, we focus on understanding the particular aspects of radio propagation in railway environments. One such aspects is the high Doppler frequency and the possibly large spread of different Doppler frequencies between differently reflected multipath reflections of the radio wave, that will cause problems in most communication systems. However, the Doppler spread can also be exploited to improve the resilience to channel variations due to fading.
