Abstract EN
This study explores the use of a hybrid Autoregressive Integrated Moving Average (ARIMA) and Neural Network modelling for estimates of the electric field along vertical paths (buildings) close to Digital Television (DTV) transmitters.
The work was carried out in Belém city, one of the most urbanized cities in the Brazilian Amazon and includes a case study of the application of this modelling within the subscenarios found in Belém.
Its results were compared with the ITU recommendations P.
1546-5 and proved to be better in every subscenario analysed.
In the worst case, the estimate of the model was approximately 65% better than that of the ITU.
We also compared this modelling with a classic modelling technique: the Least Squares (LS) method.
In most situations, the hybrid model achieved better results than the LS.
