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 intersection is presented in this paper. The model is based on experimental data at a field experiment. To adapt the model to variation of the road parameters such as a road width and a distance to the intersection, the dependence of the propagation loss characteristics on the parameters are analyzed using a path loss estimation model which has already been proposed. The analyzed results are included into the experimental propagation characteristics to improve the estimation accuracy.
