In this paper second order statistics of SC (Selection Combining) macrodiversity system's output in the presence of Nakagami-m fading are analyzed. Macrodiversity system of SC type consists of two microdiversity systems and selection is based on their output signal's average power values. Each microdiversity system is of SC type with N branches in the presence of Nakagami-m fading. Average powers at the output are modeled by Γ distribution. We have derived and graphically presented results for LCR (Level crossing rate) and AFD (Average Fading Duration) at the output of this system.
