Stochastic Spatio-Temporal Modelling of Rain Attenuation for Propagation Studies

As the impairments due to rain on the propagation channel for frequency bands such as Ka or Q/V have to be compensated by adaptive fade mitigation techniques. Optimized radio resource management needs to be implemented which requires a coarse knowledge of spatio-temporal dynamic of the attenuation due to rain. For that purpose realistic simulators of space-time correlated time series of attenuation are needed to optimize resource allocation procedures. Using outputs from general circulation models (GCM), a convenient way to extend the range of validity of existing stochastic rain and attenuation field simulators and to control some parameters such as the rain coverage or advection direction and speed is presented.
