Abstract

Propagation Impairments Mitigation Techniques (PIMTs) are necessary for satellite-based systems (typically operating at frequencies above 20 GHz) intended to provide large bandwidth to the end users. This contribution presents the best performing space-time channel model to be used in the design and control of adaptive SatCom systems. First, models able to predict the spatial distribution of the rain intensity over large (continental) areas are presented and their performance assessed against extensive radar databases. Space rain field generators are also shown to be of key importance for the control of an on-board power allocation system of a satellite equipped with a reconfigurable antenna. Finally, this contribution presents the performance of two space-time rain field generators in estimating the throughput of a simplified geometry of an Interactive MultiMedia Broadband Service (IMMBS) system implementing ACM.
