A Recursive Street Canyon Model for Low Height Terminal System

Abstract

A novel recursive street canyon model is proposed for propagation in low height terminal system. This model combines a street canyon method and a recursive method together, describing the path loss of all street types (LOS, NLOS1, NLOSn) with a unifled expression. Related parameters in the expression, such as recursive distance, street intersection number, street intersection orientation, street intersection separating distances, are achieved by a simplifled ray tracing platform which considers only one ray along each street. Compared with present street canyon model and recursive model, this proposed model not only has a much simpler expression but also shows a higher prediction precision. DOI: 10.2529/PIERS061018143810
