Space-Time Channel Model for Rain-Affected Communication Networks

This paper presents a new comprehensive space–time model of rainfall rate and its associated rainfield synthesizer called Grid Rain Attenuation Model (GRAM). A great deal of care is placed on explicitly including the rain/no rain condition so that the planning and simulation of high-frequency radio wave communication systems can be achieved with full consideration of rain intermittency effects. We also look in some details at the modification of the first- and second-order statistical descriptions of the rain precipitation rate upon the application of space and time integration to point rainfall rate.
