Abstract:Communications between vehicles is one of the most important prerequisites for inter-vehicle coordination, a key feature needed to enable autonomous and semi-autonomous driving, from an efficiency, convenience and safety perspective. Such communication will have to be done with very low latency, which lead the industry into looking at mm-wave bands, where much larger chunks of bandwidth are available. To understand the different implications of mm-wave propagation in Vehicle-to-Vehicle scenarios (V2V), channel sounders have to be built, and double-directional channel models have to be extracted, in a wide variety of scenarios and environments. In the line of this project, the authors perform measurement campaigns for a variety of situations, based on a novel channel sounder capable of measuring a full double-directional channel. The authors also provide extracted parameters such as the directional RMS delay spread and angular spreads on both Tx and Rx, that are a requirement for intelligent vehicles system development.
