Effect of UWB channel time delay parameters on TDOA localization

In this paper, we present a time delay analysis for indoor localization based on time difference of arrival (TDOA) algorithm, where we have performed both simulative and practical experiment together. Besides, we introduce the different channel parameter effects for line of sight (LOS) and non-line of sight (NLOS) scenario in indoor environment. This time delay analysis can be useful to understand the behavior of indoor channels and to choose the perfect technology for indoor localization. Results show remarkable effects of delay in TDOA localization in such environment. In addition, these results give enough information for improving localization techniques.
