pp: 1175-1179A Neural Network Approach to the Prediction of the Propagation Path-loss for Mobile Communications Systems in Urban EnvironmentsSotirios P. Sotiroudis, Katherine Siakavara, and J. N. Sahalos doi:10.2529/PIERS070220023434 Downloads: 1486 Abstract:This paper presents an alternative procedure for the prediction of propagation path loss in urban environments. It is based on Neural Network (NN) algorithms and uses the detailed environment profile instead of the mean values of its structural parameters. The general performance of the NN shows its effectiveness to yield results with satisfactory accuracy in short time. The received results are compared to the respective ones yielded by the Ray-Tracing model and exhibit satisfactory accuracy either for uniform or for non-uniform distribution of the manmade structured environment.References:1.
