Abstract:	Time of arrival (ToA) based localization by terrestrial cellular mobile radio as a complement to global navigation satellite systems (GNSSs) has gained significant attention. Still, current state of the art channel models for mobile radio are not considering important factors for the application of positioning. One of these factors is the non line-of-sight bias for a range estimate introduced in cases where the direct signal between the transmitter and the receiver is blocked. Moreover, the coherent combination of a mobile radio and a land-mobile-satellite (LMS) channel model for data fusion algorithms is missing so far. In this paper we contribute in two aspects: We propose an extension of the well known WINNER channel model which fulfills the requirements for positioning applications and, additionally, a coherent combination to the LMS channel model developed at the German Aerospace Center (DLR). A validation based on power delay profile indicates that the proposed extended model is statistically consistent with the original WINNER model.
