Wideband Channel Modeling for mm-Wave inside Trains for 5G-Related Applications

الملخص EN

Passenger trains and especially metro trains have been identified as one of the key scenarios for 5G deployments.

The wireless channel inside a train car is reported in the frequency range between 26.5 GHz and 40 GHz.

These bands have received a lot of interest for high-density scenarios with a high-traffic demand, two of the most relevant aspects of a 5G network.

In this paper we provide a full description of the wideband channel estimating Power-Delay Profiles (PDP), Saleh-Valenzuela model parameters, time-of-arrival (TOA) ranging, and path-loss results.

Moreover, the performance of an automatic clustering algorithm is evaluated.

The results show a remarkable degree of coherence and general conclusions are obtained.
