چکیده

Probability density function (PDF) ,moments of signal and amount of fading (AF) at the output of macrodiversity system in closed form are obtained. Dual maximal-ratio combining (MRC) is implemented at the micro level (single base station) and selection combining (SC) with two base stations (dual diversity) is implemented at the macro level. This model assumes a Nakagami-m density function for the envelope of the received signal and a gamma distribution to model the average power to account for the shadowing. The results are shown graphically for different signal and fading parameters values. Key-Words:Shadowing, Nakagami-m Fading, Microdiversity, Macrodiversity, Probability Density Function, Amount of Fading * Involved in project TR-21035
