Abstract-In this paper some new experimental results about the statistical characterization of the non-line-oJ-sight (NLOS) bias affecting time-oj-arrival (TOA) estimation in ultrawideband (UWB) wireless localization systems are illustrated. Then, these results are exploited to assess the performance of variousmaximum-likelihood (ML) based algorithms for joint TOA localization and NLOS bias mitigation. Our numerical results evidence that the accuracy of all the considered algorithms is appreciably influenced by the LOSINLOS conditions of the propagation environment.
