Abstract
A realistic performance assessment of any wireless communication system requires the use of a fading channel model that reflects its main characteristics. The traditional Rayleigh and Nakagami-m models have been (and still are) the basis of most theoretical research on wireless technologies today, even for emerging technologies, such as millimeter-wave communications (mm-Wave). In this article, through the use of the mean square error statistical test, we show that the FMR and κ-μ shadowed models fit better to field measurements in outdoor environments at 28 GHz than the conventional channel models. Therefore, these generalized models are introduced as a physically feasible alternative that can be used as a benchmark when evaluating communications performance in mm-Wave scenarios.
