Abstract:
The macrodiversity system reduces long term fading effects and short term fading effects on wireless system performances simultaneously. The received signal is subjected to Nakagami-m short term fading and Gamma correlated long term fading resulting in signal envelope and envelope average power variation, respectively. The macrodiversity considered in this paper has macrodiversity selection combining (SC) receiver and two microdiversity SC receivers. Signal envelope average power at inputs in microdiversity SC receivers have correlated Gamma distribution with different average values. Level crossing rate of macrodiversity SC receiver output signal envelope is evaluated for the case that the user is at different distances of microdiversity SC receivers.
