Abstract
In this Letter, the first-order Markovian assumption for the description of the dynamic behaviour of rain attenuation is validated by means of information theoretic metrics. An accurate first-order Markov model with parameters calculated by physical inputs is also presented. The proposed method is verified by a stochastic analysis of the first-order distribution and the autocorrelation function (ACF) of the model compared to experimental data.
