Abstract

This letter describes the application of rain attenuation time series synthesizers to terrestrial links in tropical regions. A model based on the Gamma distribution is developed and results are compared to those obtained with a lognormal synthesizer. The model parameters were retrieved from data collected during two years of experimental measurements at terrestrial links operating at 15 GHz. Long-term statistics of rain attenuation and fade slope obtained from synthesized time series are tested against the corresponding ones derived from experimental data. Useful empirical expressions for the synthesizers dynamics parameters are derived.
