Study and test of rain attenuation time series synthesizers for tropical and equatorial areas

To develop and test real-time Fade Mitigation Techniques control algorithms, propagation time series are needed. An alternative to using real data collected from propagation experiments is to generate typical fading time-series making use of climatological characteristics as well as geometrical and radio-electrical parameters of the link. The aim of this paper is to present and validate rain attenuation time series synthesizers relying on the Maseng-Bakken principle and 2-state Markov chains for tropical and equatorial areas. Brazilian beacon data at 11.5 GHz are used to parameterize and test the models. The three long-term models are tested with respect to long-term statistics and an "event based" methodology is used to test the isolated events generated by the "event-on-demand" model.
