Abstract

Multipath propagation events are observed on the 50 km long fixed terrestrial link operating in 10 GHz band. Several receivers are located in different heights. Two year statistics of attenuation and enhancement due to multipath are obtained from measured signal fluctuations in different heights. The results are compared with cumulative distributions predicted by the two methods - the ITU-R method and the VUS method which is currently used for the planning of radio-relay links in the Czech Republic. The predicted distributions of attenuation provide slightly higher exceedance probabilities than measured.
