Read the ITU P. 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.

It causes misleading results related to corrections. Other MathWorks country sites are not optimized for visits from your location.

Evaluation and improvement of the field prediction method in recommendation ITU-R P.1546-3

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. I can not run PFieldStr. How do I run? You are now following this Submission You will see updates in your activity feed You may receive emails, depending on your notification preferences.

Please help is appreciated. Undefined function or variable ‘h1Calc’. The corrections are always added into field strenght. Added a graphical interface type ITUP correct minor issues. In order to calculate the propagation loss of electromagnetic waves produced by a transmitter, a variety of models based on empirical and deterministic formulas are used.
