- W2904509178 abstract "Currently, the measures to traffic accident are advanced with the spread of the automobile. This paper discusses the pedestrian positioning system based on UWB(Ultra-Wide Band) ranging. In this system, base stations to receive UWB signal that is transmitted from pedestrians are attached to a traffic light for pedestrians. Positions of pedestrians are estimated by LSM(Least Square Method) using the ranging value that is estimated by UWB ranging scheme. The slotted ALOHA scheme is adopted for multiple access to access control. UWB positioning estimation system can detect positions with the error of 40cm. However, detailed characteristics of UWB positioning estimation system is not analyzed. In this paper, positioning error and PSR(Positioning Successful Rate) of estimation system are evaluated and analyzed by computer simulations. Also, positioning error and PSR are depended on the number of base stations. Thus, the effect of increasing the number of base stations is evaluated and analyzed. As the results of computer simulations, it is shown that the position of the pedestrian can be accurately estimated by using UWB positioning system." @default.
