Level crossing rate and average fade duration of signal envelope of selection diversity are numerically determined. Statistical characterization in fading and shadowing mobile radio communication environment are very useful and in this paper that is computed for Ricean fading channels with lognormal shadowing. The results are presented for independent identically distributed diversity branches when selection combining technique is used.

Average Fade Duration

Exact and closed form expressions for the average level crossing rate (LCR) and average fade duration (AFD) of the output signal envelope of selection diversity system are derived, assuming each branch is subject to independent but nonidentical composite fading in distributed antenna systems (DAS). Numerical results validate the derived expressions. It shows that DAS promise significant diversity gains over collocated multiple antenna system.
