On the effective capacity of Fisher-Snedecor F fading channels

The performance of the effective capacity metric under Fisher-Snedecor F fading channels is investigated. To this end, a novel exact closed-form expression for the effective capacity is derived. Furthermore, in order to gain more insight, a simple asymptotic expression at the high signal-to-noise ratio regime is also provided. Additionally, expressions for the effective capacity of the Nakagami-m and Rayleigh distributions are deduced from the proposed results as special cases. The analytical results are compared to Monte-Carlo simulations to prove the correctness of the analysis. The results show that fading has a more positive influence on effective capacity performance than shadowing.
