Una solución en términos de coeficientes UTD para el análisis de la difracción múltiple de ondas esféricas en entornos urbanos sín visión directa por efecto del terreno

Abstract

A function expressed in terms of UTD coefficients for the analysis of the multiple diffraction in urban areas where a bare wedge-shaped hill causes shadowing of the transmitter from the receiver (NLOS situation) is presented. The solution, validated with numerical results from technical literature, has a good computational efficiency and increases the versatility over existing formulation allowing the study of the mentioned environment when a small number of buildings are considered as well as when a sphericalwave incidence over these latter is assumed.
