The asymptotic behavior of the derived expressions is also analyzed providing direct and concrete insights on the role and effect of the involved parameters on the ED performance.

To this end, it is shown that the detrimental effects of fading can be effectively mitigated with the aid of square-law combining and switch-And-stay combining methods, as a low number of diversity branches can ensure sufficient and holistic performance improvement even in severe fading conditions.",
