Abstract :
Proposes a model of space diversity improvement for line-of-sight microwave radio against outage during multipath fading caused by thermal noise. The diversity improvement factor (DIF) predicted by this three-day model agrees very well with the data measured from the 26-mile Atlanta-Palmetto path. The model predicts the existence of an optimum vertical separation to achieve the maximum DIF, in agreement with the measured field data. The DIF is calculated for the 4-, 6-, and 11-GHz frequency bands
