Evaluation and improvement of the field prediction method in recommendation ITU-R P.1546-3
This implementation is finished open with ITUP to view gui interface. This an implementation of the ITU-R p. In this paper, the propagation loss of FM radio station using artificial neural networks models is studied depending on the Levenberg-Marquardt algorithm.
Journal of Electromagnetic Analysis and ApplicationsVol. Select the China site in Chinese or English for best site performance. Updates 27 Aug 1. Undefined function or variable ‘step82’. 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 p.5146-3 results based on ITU-R and Epstein-Peterson models.

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 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. Comments and Ratings 9. Minor issues corrected -warm sea paths .p1546-3 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.
