| Abstract(in English) | In the current autonomous driving, the surrounding situation is always grasped by using the cameras and sensors mounted on the vehicle. However, even though there are many collision accidents in places with many blind spots such as intersections, pedestrians and vehicles cannot be recognized correctly by the method using optical information of sensors and cameras. Therefore, the authors are considering a wireless system in which a roadside machine deployed at an intersection captures a blind spot and broadcasts it to surrounding autonomous vehicles. In this paper, we propose a communication method with excellent frequency utilization efficiency by using a basic technology called pseudo-analog communication method in roadside video broadcasting, and verify the influence of changes in the spatiotemporal wireless environment on the pseudo-analog communication method. In addition, we will introduce a metadata transmission method using a mobile communication network and show its problems. |
