Equações parabólicas aplicadas ao estudo de cobertura radioelétrica em sistema de comunicação digital P-25

Abstract

The objective of this work is to study the Parabolic Equation Method, with numerical solution through the Split Step Fourier Transform method (SSFT), applying the technique to analyze wave propagation in the Metropolitan Region of Belo Horizonte. The technique, called Split Step Parabolic Equation (SSPE), was used in this work as the main tool for predicting coverage, allowing the calculation of the electromagnetic field along different trajectories on various types of surfaces. The method was applied to different scenarios and validated through real data from field measurements, using equipment to measure the signal power coming from different telecommunications sites. And, thus, the prediction data was validated with real data and with results obtained through commercial software. In addition, the functionality for generating coverage maps was incorporated into the software, enabling detailed prediction around the transmitter. This improvement makes the method even more applicable in real projects of wireless communication systems, increasing its effectiveness for network planning.
