This paper presents an empirical model for the statistical prediction of site diversity gain on earth space propagation paths. A modelling approach is described which incorporates 46 months of Nimrod rain radar data recorded in South England. The dual site diversity (SD) gain is developed as a function of several parameters, including time percentage of average year, site separation, baseline orientation,...
An improved semi-empirical method for the prediction of rain attenuation in earth space and terrestrial links is proposed. The full rainfall rate distribution is used as input for the prediction of the rain attenuation distribution in a single algorithm that is consistent for both slant and terrestrial links. The numerical coefficients in the expressions were derived by multiple non-linear regressions...
A model for predicting rain attenuation on earth-to-space is developed by using the measured data obtained from tropical and equatorial region. The proposed rain attenuation model uses the complete rainfall rate cumulative distribution as input data. It is shown that significant improvements in terms of prediction error over existing attenuation model are obtained
