Comparison of path loss and time‐delay spread in regular and chaflane street corners for microcellular communications

A ray‐tracing model based on the application of the uniform theory of diffraction (UTD) and geometrical optics (GO) for modeling the propagation in microcellular urban scenarios has been implemented. A comparison with the simulation of published results validates our model. This model has been used to analyze some propagation characteristics (path loss and rms delay spread) in two street‐corner environments—regular and chaflane street corners. The study of the environments of the two corners shows that differences in the predictions are basically caused by the rays reflected on the walls of the chaflane corners. © 2001 John Wiley & Sons, Inc.
