A Vehicle Positioning Algorithm Based on Single Base Station in the Vehicle Ad Hoc Networks
CSPS(2019)
摘要
This paper mainly designs a vehicle positioning algorithm based on single base station, which can both consider the angle and distance between the vehicle and the base station. The known vehicle location environment is free of any occlusion. The propagation loss prediction model is used to measure the distance between the base station and the vehicle according to the known transmitting power and receiving power. The uniform antenna array are installed on the base station, and the signal angle is obtained by ESPRIT algorithm. Finally, the coordinate system is constructed by using geometric model, and the coordinates of vehicles are calculated according to the triangular formula. If the speed or acceleration of the vehicle is known, the coordinates of the vehicle in the next second can be obtained through physical knowledge, so as to achieve vehicle location. By comparing with the literatures, the positioning scheme designed in this paper is more accurate than that in the selected literatures.
