摘要：

高精度车辆定位是自动驾驶、车联网中的关键技术环节，其中一个研究热点和难点是如何在高密度城市、隧道、地下车库等无法获取GPS或蜂窝网基站定位信号的区域实现低成本、高可靠的车辆精准定位。对此，创新性地提出了一种基于反向散射通信的车辆精准定位技术（即“BackCom车辆定位技术”），其仅须在车辆顶端安装一个包含 2 根天线的定位阅读器以及在道路边部署至少一个定位标签，便可实现高精度车辆定位。经仿真验证，BackCom车辆定位技术可以取得极高的定位精度。同时，BackCom车辆定位技术极易扩展，通过增加其定位阅读器中的天线数量，可进一步提升其定位精度。BackCom车辆定位技术具备低成本、低功耗、高精度、高可靠、部署方便等优点，适用于各种行车环境，具备极高的理论研究价值和商用价值。

Abstract:

The accurate vehicular positioning technology has been the fundamentalfunction for safer auto-driving and vehicular-to-everything networks.One research trend focuses on enabling the low-cost,reliable,and accurate vehicular positioning in high-density cities,tunnels,and underground where the GPS or cellular positioning can’t work due to the signaling blocking.To this end,a novel backscatter communication assisted vehicular positioning system was proposed where a backscatter-reader (with two antennas) was deployed on vehicle and at least one backscatter-tag is deployed along a roadside,based on which the location of vehicle could be estimated with ultra-high reliability and accuracy.Through simulation verification,BackCom vehicle positioning technology can achieve extremely high positioning accuracy.At the same time,BackCom’s vehicle positioning technology is very easy to expand.By increasing the number of antennas in its positioning reader,it could further improve its positioning accuracy.BackCom vehicle positioning technology has the advantages of low cost,low power consumption,high accuracy,high reliability,and easy deployment.It is suitable for various driving environments and has extremely high theoretical research value and commercial value.

Key words: vehicular positioning technology, backscatter communication, vehicular-to-everything and autonomous driving, internet-of-things technology, waveform design and signal processing
