This an implementation of the ITU-R p. The corrections are always added into field strenght. Updates 27 Aug 1. I can not run PFieldStr. Undefined function or variable ‘h1Calc’.

Based on your location, we recommend that you select: Comments and Ratings 9. Scientific Research An Academic Publisher. 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.

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. Undefined function or variable ‘step82’. This was created from ITU p.

Read the ITU P. It causes misleading results related to corrections. Minor issues corrected -warm sea paths are now selected -step 15 implemented with environment set values instead of any R value -values are selected from a preloaded entry rather than the excel.

The good results obtained in the city area reveal that the artificial neural network is a very efficient method to compute models which integrate theoretical and experimental data. Mixed land a sea paths not implemented. Artificial Neural NetworkPrediction of Propagation.

Added a graphical interface type ITUP correct minor issues.
