Abstract
The characteristics of propagation channels between high-speed trains and fixed base stations for multimedia communications links using orthogonal frequency division multiplexing (OFDM) is investigated. To model the system behaviour realistically, impulse responses of the transmission channels are generated by a ray-tracing tool. Typical environments along a railway track are taken into account as well as the train motion. Mobile station antennas with different patterns are included in the simulation model and the results are compared and assessed with respect to characteristic channel parameters.
