Assessment of rain fade mitigation techniques for high throughput satellites by a time series synthesizer

We assess here the effectiveness of fade mitigation techniques on the user link side of a TLC satellite system by a simulation tool able to generate correlated time series of rain attenuation in multiple sites. A preliminary analysis of two case studies shows that on-board dynamic power allocation coupled with ACM reduces the impact of heavy fades, permits a larger exploitation of efficient MODCODs and equalizes the performance of the user links. However, in the presence of convective cells, co-channel interference can be dominant, hence reducing the benefits of the above techniques.
