Abstract
The design and optimization of fade mitigation techniques in Q/V bands satellite communications require rain attenuation time series. Methods for synthesizing short-term and long-term rain attenuation time series at Q/V bands are integrated in this paper. Firstly, based on the ‘Event-on-Demand’ model, the rain attenuation process is transformed into a first-order stationary Markov process after nonlinear transformation. The generation steps of short-term rain attenuation time series are analyzed. Then, the principle of Dirac-lognormal distribution model is analyzed, and the steps of generating long-term rainfall attenuation time series are given. Finally, the short-term and long-term rain attenuation time series at Q/V bands are obtained through simulation. The power spectrum estimation of the series shows the validity of the rain attenuation time series.
