Simplified prediction of propagation loss over non line-of-sight intersections in V2V

A simplified prediction scheme of averaged propagation loss over an NLOS intersection in V2V is proposed. In the scheme, the propagation loss is calculated by accounting only the dominant paths in the ray-tracing calculation. In this paper, the calculation method is presented and its accuracy is evaluated by comparing the predicted results with those by the ray-tracing method. As the result, we show the proposed method effectively estimates the propagation loss close to that by the ray-tracing.
