Second-Order Statistics in Weibull-Lognormal Fading Channels

Aleksandra M. Cvetkovic, Marjan M. Jakovljević

Abstract

This paper considers second-order statistics of the received signal envelope in fading and shadowing mobile radio environments. Stochastic process is modeled as a product of a Weibull and lognormal process. Expressions for level crossing rate and average fade duration for signal envelope, characterized by Weibull fading and lognormal shadowing, are derived. Fading parameter and shadow effects that affect this statistics are presented graphically.
