Satellite and Terrestrial Links Rain Attenuation Time Series Generator for Heavy Rain Climatic Regions

A new stochastic dynamic model for the generation of rain attenuation time series for fixed satellite and Line-of-sight (LOS) terrestrial links operating above 10 GHz is presented. The model's concept originate from the classic Maseng-Bakken (M-B) approach apart that it generates Gamma distributed rain attenuation time-series and not lognormal as in M-B approach. Gamma-distributed links are typical at heavy rain climatic regions where the new model is expected to perform better than the M-B. The comparison with experimental results in terms of exceedance probability is very encouraging.
