Positioning Algorithm Using OFDM
Hideaki Shiranaga, Shouhei Ogawa (SEI) ITS2008-2
Abstract (in Japanese) (See Japanese page) 
(in English) Recently, driver safety support systems in ITS have been developed. High accurate positioning enables us to realize these systems, but the positional accuracy of present car navigation system is not adequate. Therefore, we consider the possibility of using radio signals for positioning vehicles, and hope to improve the positioning accuracy by fusing it into current navigation systems. For details, this paper reports the new positioning method using OFDM. we estimate delay profile from received signal by least-square method, and calculate the arrival time of radio signals and the distance from roadside unit to vehicle with a high degree of accuracy. In addition, we evaluate this proposed new positioning algorithm by computer simulation, and compare it to common positioning algorithm.
