Abstract
The extremely fine time resolution of the ultra-wideband (UWB) signal enables accurate ranging based on time delay estimation. However, the possibility of an anomalous estimation can be a serious problem for accurate ranging. In the presence of a large number of multiusers, the probability and the variance of a large error can be significant. In this paper, an analysis of the UWB ranging performance in the presence of large error is posed. Both analytical and experimental approaches are taken to evaluate the large error variance in a correlation-based serial search scenario.
