In this paper, various positioning algorithms for range-based TOA and TDOA localization have been analyzed, which include the analytical method, least square method, approximate maximum likelihood method, Taylor series method, two-stage maximum likelihood method and genetic algorithm. The assumed scenario is an overdetermined system in a 3D space under line of sight (LOS) situation and a number of...
This paper presents verification results of an advanced 3-D ray tracing model in a macrocell urban environment The verification is based on wide-band double-directional channel measurements at a center frequency of 5.2 GHz and a bandwidth of 120 MHz. For the verification two site-specific measurement routes in the city center of Karlsruhe, Germany are used. Both, the wide-band and the directional...
