چکیده :

The validation of statistical models for the direction of arrival (DoA), time of arrival (ToA), and received power in a simple indoor Terahertz channel has been investigated. At Terahertz frequencies, surface roughness can be in the order of the Terahertz frequency spectrum wavelength, so the effect of diffuse scattering must be considered in channel modeling. Therefore, a complete simulation of common indoor materials, including gypsum plaster, MDF, PVC, and glass, has been accomplished using the method of moments (MoM) at 100 GHz for TE-polarized incident plane wave, considering the surface roughness. Subsequently, simulation results have been combined with the ray tracing (RT) algorithm to perform a site-specific propagation analysis on a simple indoor scenario and to calculate the DoA, ToA, and received power histogram of all received rays. Finally, a suitable statistical distribution has been matched to the acquired histogram.
