Abstract

Several traditional models exist to describe the multipath phenomenon in wireless communications, such as Rice, Nakagami-m, Hoyt, and Rayleigh. There are other new ones that propose a generalization in order to better fit fading environments, such as α-µ, κ-µ and η-µ. In this work, the κ-µ extreme distribution, a special case of the κ-µ fading channel, is investigated. The statistical characterization of the κ-µ extreme fading parameter, m, is presented, considering both indoor and outdoor field trial measurements. More specifically, the empirical probability density function and the autocorrelation function of the fading parameter of the κ-µ extreme distribution are obtained. Moreover, from the empirical data, the range of possible practical values is also obtained and discussed. Finally, the instantaneous magnitude variation of m considering the mobile receiver displacement is estimated. The results presented here provide important information about the actual usefulness of the κ-µ extreme fading model in mobile communication systems.
