Long Term Evolution (LTE) is expected to substitute
the Global System for Mobile Communications (GSM) as the
radio access technology for railway communications. Recently,
especial attention has been devoted to high-speed trains since
this particular environment poses challenging problems in terms
of performance simulation and measurement. In order to severely
decrease the cost and complexity of high-speed measurement campaigns,
we have proposed a technique to induce effects caused by
highly-time varying channels on Orthogonal Frequency-Division
Multiplexing (OFDM) signals while conducting measurements at
low speeds. In this work, we evaluate this technique by comparing
the results of LTE measurements at different velocities as well
as by simulations. Additionally, we use this technique to show
the performance of LTE for high-speed train scenarios up to
600 km/h. To accomplish this, we use both a controlled highspeed
measurement setup as well as a channel model developed
according to the guidelines of the ITU Radiocommunication
Sector (ITU-R) for the evaluation of radio interface technologies
for IMT-Advanced systems.
