Millimeter-wave(mmWave) Beamforming(BF) for high speed trains(HSTs) scenario has been investigated in this paper. Throughout the paper, We have designed a patch antenna array and BF Scenario for HSTs, the analysis of path loss, received power and Rician k-factor are obtained with ray tracing simulator at 60GHz band. In summary, we have gained valuable results in adaptive BF based HSTs communication.
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...
