交通流量和交通事故的增长对无线通信和定位技术提出了越来越多的要求，这些技术可以提供新的服务，例如车辆碰撞警告和交通管理。目前，全球卫星定位系统、北斗卫星定位系统等全球导航卫星系统在车辆上应用广泛，在平坦开阔地区定位精度较高。然而，全球导航卫星系统只能在视线范围内工作，在非视线范围的隧道或经常发生卫星信号阻塞的闹市区，它无法工作。针对全球导航卫星系统的不足，提出了采用IEEE 802.11p短前导码的无线测距或定位系统。通常，准确的到达时间估计对于定位估计是非常重要的。为了提高到达时间估计的精度，提出了一种基于IEEE 802.11p短前导码的相关和偏差测距方法。仿真结果表明，在加性白色高斯噪声信道和国际电信联盟车辆环境多径信道中，该方法具有较好的精度和较低的复杂度，特别是在低信噪比时。
Growth of the traffic flow and traffic accident has raised more and more demands on wireless communication and positioning technologies that can provide new services such as vehicle collision warning and traffic management. Currently, the global navigation satellite system such as global positioning system and BeiDou satellite positioning system is widely used in vehicles and is fairly accurate in flat open areas. However, the global navigation satellite system can only work in line of sight environment, and it fails to operate in non-line of sight tunnels or downtown areas where blockage of satellite signals is frequent. Because of the shortages of global navigation satellite system, the wireless ranging or positioning system using the short preamble of IEEE 802.11p is provided. Typically, accurate time of arrival estimation is very important for positioning estimation. In order to improve the precision of the time of arrival estimation, a correlation-sum-deviation method for ranging using the IEEE 802.11p short preamble is proposed. Simulation results are presented which show that in both the additive white Gaussian noise channel and the international telecommunications union multipath channel for vehicular environments, the proposed method provides better precision and is less complex than other techniques, particularly when the signal-to-noise ratio is low.
