A Propagation Path Loss Model for NLOS Vehicle to Vehicle Communications at an Intersection: An Improvement of Empirical Path Loss Model Based on Theoretical Analysis

摘要

A propagation path loss model for NLOS vehicle to vehicle communications at an intersectionrnis presented in this paper. The model is based on experimental data at a field experiment. Tornadapt the model to variation of the road parameters such as a road width and a distance to thernintersection, the dependence of the propagation loss characteristics on the parameters arernanalyzed using a path loss estimation model which has already been proposed. The analyzedrnresults are included into the experimental propagation characteristics to improve thernestimation accuracy.
