Abstract :
In this work the time-domain uniform theory of diffraction (TD-UTD) is applied to the characterization of radio channels in urban environments. Early-time approximations are employed to heuristically establish TD-UTD coefficients for the analysis of the diffraction by dispersive obstacle wedges
