Physical-layer security over generalised-K fading channels

abstract

• The Institution of Engineering and Technology. In this study, the secrecy performance of the classic Wyner's wiretap model over generalised-K fading channels is studied. The closed-form expressions for the average secrecy capacity, the lower bound of secure outage probability, and the probability of strictly positive secrecy capacity are derived. The new expressions provide a unified form, which can handle several of the well-known composite fading environments as special or limiting cases. Moreover, all the derived expressions are given in terms of Meijer's G-function, which can be simply realised in MATLAB and MATHEMATICA. Monte-Carlo simulations are performed to verify the proposed analysis models.
