Abstract :
The Weibull distribution is a flexible statistical model for describing multipath fading channels in both indoor and outdoor radio propagation environments. A new closed-form expression is derived for the moment generating function of the Weibull distribution, valid when its fading parameter assumes integer values. The performance of digital linear modulations operating on Weibull channels is studied. Expressions for the signal outage and average symbol error rate are derived for single-channel reception and multi-channel diversity reception operating on Weibull fading channels.
