Analysis of propagation conditions at 20 and 30 GHz in Europe
Abstract
Rain attenuation, depolarization and gain due to reception diversity are studied for transmission from a geostationary satellite to Europe in the 20 to 30 6Hz frequency band. These characteristics are established by available date, prevision methods or frequency transposition laws. It is found that the CCIR prevision method is best suited to forecast attenuation in the 20 to 30 6Hz band, and demands the knowledge of the 0.01% rain intensity only. The curves estimating the diversity gain as a function of several parameters are presented.
