Parabolic Equation Technique Applied to an Urban Scenario in Rio de Janeiro

In this paper, the discrete-mixed Fourier-transform parabolic equation (DMFT/PE) technique was applied to predict the path loss in an urban scenario. Preliminary results for the numerical prediction is presented, using the algorithm in an urban scenario, in Rio de Janeiro, Brazil, at frequencies related to 5G. The topography and the presence of buildings were considered in the numerical simulation, as the ground loss and the electrical parameters of the buildings were included in the PE algorithm to predict the path loss. A root mean square error comparison was performed for two different spatial samplings: in the first case all the measured points were considered in the PE prediction and in the second case only points with a distance of 50 m between them. The use of the parabolic equation to predict the path loss prediction in urban measurements seems to be very promising as the obtained RMSE between measurements and simulation was 8.5 dB at maximum in contrast with 10.3 dB when using classic Hata Prediction.
