Abstract
Recently, impulse radio-ultra wideband is widely used for highly accurate location estimation of robots and objects in indoor space for building automation. For their accurate positioning, calibration must be performed after the positioning system is installed, and a compensation technique of the multipath signals should be performed in real-time. In this paper, a real-time calibration and error compensation method is proposed. A filter that estimates channel common error and channel-specific error sequentially is designed based on cubature Kalman filter and the fast and accurate estimation performance of this filter is verified experimentally.
