Meanwhile, the results show that an ANN model performs very well compared with theoretical and empiric propagation models with regard to prediction accuracy, complexity, and prediction time. Please help is appreciated. Select itur- China site in Chinese or English for best site performance. Artificial Neural NetworkPrediction of Propagation.

Minor issues corrected -warm sea itu-rr are now selected -step 15 implemented with environment set values instead of any R ifu-r -values are selected from a preloaded entry rather than the excel. How do I run? Updated 27 Aug Edgar Castillo Edgar Castillo view profile. How the program works please? The corrections are always added into field strenght. In this study, one of the artificial neural networks models, Levenberg-Marquardt algorithm, which is quite effective for predicting the propagation is used and the results obtained by this algorithm are compared with the simulation results based on ITU-R and Epstein-Peterson models.

In order to calculate the propagation loss of electromagnetic waves produced by a it-ur, a variety of models based on empirical and deterministic formulas are used.
