Position Localization with Impulse Ultra Wide Band

Abstract

In this paper, a low cost UWB-based position localization experiment system is designed and tested in the indoor environment. And a delayed-correlation detector and ultra-highspeed 1bit ADC are proposed to mitigate the estimation error of time difference of arrival (TDOA). And an algorithm using parallel processing and direct path tracking is also proposed to remove the timing-of-arrival (TOA) bias and clock jittering error of TDOA measurement. In our prototype design, we exploit impulse UWB techniques to implement a very low cost localization system that can achieve centimeters localization for indoor applications. The design shows good performance even in heavy multipath indoor environment.
