The Folded Normal Distribution: A New Model for the Small-Scale Fading in Line-of-Sight (LOS) Condition [PDF]
IEEE Access, 2019 [EN] In this paper, a novel form of the folded normal (FN) distribution has been proposed to model the small-scale fading in wireless communications. From a multiple-input multiple-output (MIMO) measurement campaign conducted in a lab environment with the line-of-sight (LOS) conditions at both the 60 and the 94 GHz bands, the authors obtain the ...
