Abstract :
Path-loss characteristic at 38 GHz in a one-way semicircular subway tunnel is attained by means of experiment. Based on the result, simulation parameters, such as roughness, permittivity and conductivity, are attuned exactly. Detailed researches for small-scale fading characteristic at 38 GHz in this subway tunnel are performed using simulation tool based on ray tracing theory. Some significant conclusions are resulted from experiments and simulations.
