Abstract

Ultra-wideband (UWB) signals can be used for accurate time of arrival (TOA) based ranging because of their high time resolution. In this paper, a novel data-aided TOA estimation method is presented using dual pulse (DP) signal structure. It employs received signal autocorrelation and threshold crossing to detect the direct path. The effects of different threshold values and training sequence lengths on the estimation accuracy of the proposed method are studied. The performance improvement of this approach over the conventional energy detection based method is also demonstrated via simulation.
