Near-optimum short-term fade prediction on satellite links at Ka and V-bands

摘要

Several short-term predictors of rain attenuation are implemented and tested using data recorded from a satellite link in Southern England, and a comparison is made in terms of the root-mean-square error and the cumulative distribution of under-predictions. A hybrid of an autoregressive moving average and adaptive linear element predictor is created that makes use of Gauss-Newton and gradient direction coefficient updates and exhibits the best prediction error performance of all prediction methods in the majority of cases.
