The к-μ Extreme distribution: Characterizing severe fading conditions

This paper presents the κ-μ Extreme fading distribution, which is used for characterizing mobile radio propagation under severe fading conditions. The distribution is adjusted to field data extracted from the literature and compared to another model recently proposed elsewhere, namely the Two-Ray model. Adjustment results show that the κ-μ Extreme distribution is flexible and suitable to model the severe fading conditions. A closed-form expression for the average BER in non-coherent binary modulation schemes is derived. Finally, performance of the selection combining technique is evaluated in terms of the outage probability.
