In this paper, ray tracer (RT) is employed to simulate the propagation in a high-speed railway viaduct scenario at the frequency of 93.2 GHz. By comparing the path loss between simulation and measurement, the permittivity and loss tangent of concrete which is the material of viaduct are calibrated in the ray tracer. The average error between calibration result and measurement is 0.2 dB. The calibrated...
Long Term Evolution for Railway (LTE-R) is commonly believed to be the next generation wireless communication system for high speed railway. The main objective of this paper is to assess the performance of LTE-R under realistic conditions using a hybrid high speed railway channel model involving WINNER II Channel Model that was refined and validated using measurements made within the WP1 Channel Model...
