Fading Modeling in Indoor THz Wireless Systems

Abstract

This contribution aims at experimentally validating the suitability of well known fading distributions in modeling the channel of indoor THz wireless systems. In particular the suitability of α–μ, Rice and Nakagamim distributions is evaluated by fitting them to empirical channel measurements. The fitting performance is expressed in terms of the Kolmogorov-Smirnov (KS) and Kullback-Leibler (KL) divergence tests. The results show that the α–μ and Rice distributions achieve a good fit to the empirical data, wheras the Nakagami-m distribution fails to provide an adequate fit in the majority of the examined THz links.
