Abstract: | In this paper we proposed the results of average LCR (level crossing rate) and AFD (average fading duration) criterions applied
to evaluate the performance of dual-branch SC (selection combining) reception in the specified fading channels characterized
as statistical distributions with correlated-Rayleigh and correlated-Rice models. Moreover, in order to unify and clarify
the criterions of performance formulas with average LCR and AFD for SC diversity over different kinds of fading models, include
such as Rayleigh, Rice, Nakagami-m, and Weibull distributions etc., almost all of the ever researched and published results from discussing about the LCR and
AFD of SC diversity are comprehensively collected in this report. On the other hand, for the purpose of comparison, there
are a large number of LCR and AFD performance formulas for SC diversity and the generalized fading statistic models are extracted
and tabulated together, in which the cases of correlated and independent proprieties between diversity branches are taken
into consideration too (some of the formulas are illustrated by the assumption of dual-branch SC diversity).
