AB - A study of the influence of building modeling
when predicting the signal attenuation due to overrooftop
multiple diffraction in urban environments is
presented. A straightforward formulation expressed in
terms of Uniform Theory of Diffraction (UTD)
coefficients is used for the above-mentioned analysis
assuming a spherical-wave incidence over the array of
buildings and considering the latter modeled as series of
different representations such as knife edges, double
knife edges, wedges and rectangular sections. The results
clearly indicate the importance of an appropriate
building modeling in obtaining realistic path-loss
predictions in urban environments when multiple
diffraction has to be considered.
