Effective capacity of communication systems over $\kappa$-$\mu$ shadowed fading channels

Abstract

The effective capacity of communication systems over generalized $\kappa$-$\mu$ shadowed fading channels is investigated in this letter. A novel and analytical expression for the exact effective capacity is derived in terms of extended generalized bivariate Meijer's-$G$ function. To intuitively reveal the impact of the system and channel parameters on the effective capacity, we also derive closed-form expressions for the effective capacity in the asymptotically high signal-to-noise ratio regime. Our results demonstrate that the effective capacity is a monotonically increasing function of channel fading parameters $\kappa$ and $\mu$ as well as the shadowing parameter $m$, while it decays to zero when the delay constraint $\theta \to \infty$.
