Fade statistics in Nakagami-lognormal channels

New expressions for the average Level crossing rate (LCR) and average time fade duration (AFD) of signal envelope in microcellular mobile radio channe ls, characterized by Nakagami fading and lognormal shadowing, so called Nak agami-lognormal (NLN) channels, are derived. New LCR and AFD are computed, and the effects of Nakagami m factor and shadowing spread sigma(S) on these fade statistics are discussed. The generality of the NLN model is demonstr ated by matching some LCR curves with recently reported measurement [18] fo r the land mobile satellite channel, commonly described as the Rice-lognorm al channels.
