Terrestrial rain attenuation time series synthesizers for tropical regions

the aim of this paper is to present and validate rain attenuation time series synthesizers relying on the maseng-bakken principle for terrestrial links in tropical areas. data obtained in experimental measurements at four links operating at 15 ghz in s？o paulo, brazil, are used to parameterize the synthesizers. two models are tested with respect to long-term statistics including cumulative distributions of rain attenuation, fade durations and fade slope.
