Abstract

This work proposes and conduct a practical investigation on the a probability density function of the α-µ/Gamma composite distribution, obtained in closed-form expression, for the multipath shadowed fading channel in wireless environments. The statistical characterization includes both theoretical models and practical investigations through field measurements. More specifically, the analyses was realized for the mobile radio channel operating in the frequencies 780 MHz, 1800MHz and 2500 MHz. A transmission and reception system was specially designed for field measurements and a software for processing the captured data was built. The practical data are confronted with the theoretical data obtained from the α-µ/Gamma distributions and very good fits are found.
