Average level crossing rate and average fade duration of MRC and EGC diversity

The average level crossing rate and average fade duration of the output signal of a maximal ratio combiner and equal gain combiner, operating on independent Ricean (1940) fading input branch signals are derived. Exact, closed-form results are obtained for MRC diversity, while exact expressions for EGC diversity are presented with an infinite series method. The results are valid for an arbitrary number of independent, identically distributed diversity branches.
