Effective capacity of communication systems over κ–μ shadowed fading channels

The effective capacity of communication systems over generalised κ–μ shadowed fading channels is investigated. A novel and analytical expression for the exact effective capacity is derived in terms of the extended generalised bivariate Meijer's-G function. To intuitively reveal the impact of the system and channel parameters on the effective capacity, closed-form expressions are derived for the effective capacity in the asymptotically high signal-to-noise ratio regime. The results demonstrate that the effective capacity is a monotonically increasing function of channel fading parameters κ and μ as well as the shadowing parameter m, while it decays to zero when the delay constraint θ → ∞.
