A novel geometry-based channel model (GCM) for line-of-sight (LoS) microcell scenario in dense urban areas is proposed. The proposed two dimensional scattering power distribution (SPD) is postulated on the physical phenomenon is obtained. The implementation issues are discussed and the delay-power spectrum (DPS) and azimuth-power spectrum (APS) derived from the proposed model are compared to those for conventional elliptical models as well as to the experimental results. The superior prediction of the proposed model in contrast to the conventional models is demonstrated.
