Prediction Model for the Effective Operation of Earth-space Links Using Up-Link Power Control

摘要

A new model for the application of Up-Link Power Control in satellite communication systems is presented. The model consists in the combination of an ARIMA model to forecast the rain rate (5 minutes in the future) and of the Enhanced Synthetic Storm Technique (E-SST) to generate time series of the rain attenuation at two frequencies, from which the frequency scaling ratio can be calculated for the real time application of Up-Link Power Control. The performance of the model, tested against the Alphasat Ka- and Q-band propagation data collected in Milan, indicate that the proposed frequency scaling approach is accurate enough to allow the real-time effective application of ULPC in EHF satellite communication systems.
