Modeling and simulation of wideband radio channel characterization for an urban line-of-sight microcell

This paper presents a proposed model in an explicit form and its simulation results for characterizing wideband line-of-sight (LOS) radio channel in an urban microcellular environment. The model is fast to compute, easy to implement, and only those rays that reach the receiver locations are calculated. Effects of street grid, with any number of crossing streets of different widths, on the propagation characteristics can be studied. The model provides details of possible radio paths that join the base station with the mobile terminal at any point in the main street. The characterization of the channel is presented in three domains. They are: frequency, temporal and angular domains. The model can be used to study several microcellular communication problems
