Secrecy Capacity of $\kappa-\mu$ Shadowed Fading Channels

Abstract

Secure outage probability and strictly positive secrecy capacity (SPSC) expressions are derived for single-input multiple-output systems over κ - μ shadowed fading channels. Also, a novel approximation for the SPSC is derived in terms of a single Gauss hypergeometric function. A close match is observed among the results obtained through the derived analytical expressions, the approximation, and Monte Carlo simulations.
