Abstract
In this paper, we show the characteristics of the threshold-based IR-UWB location positioning system by experiment. We found that this system provides distance-dependent accuracy because the arrival time of the pulse is detected by threshold using 1-bit ADC (Analog to Digital Convertor). We also propose a simple compensation method based on measurement to improve positioning accuracy. The proposed method improves positioning error down to 52.7%.
