Probability of strictly positive secrecy capacity of the Weibull fading channel

Abstract

In this paper, the information-theoretic secrecy of Weibull fading channels is investigated. The present work generalizes the analysis on Rayleigh fading. Several formulas of the probability of strictly positive secrecy capacity are derived. It is shown that in some cases the results can be expressed in terms of a general function, the Meijer G-function. Profile examples are illustrated and discussed.
