  Abstract

In this paper, we evaluate the impulsiveness of the cross-correlation between the user signals for asynchronous time-hopping and direct-sequence ultra-wideband (UWB) transmissions and examine its effect on UWB ranging. It is conventional to measure variance of cross-correlation for interference analysis. However, kurtosis, a parameter indicating the impulsiveness, was utilized in this work. Considering the ranging applications of UWB systems, the impulsiveness of multiuser interference is critical. When an independent and identically distributed random spreading code was used, the variance for the two scenarios was shown to be similar but the kurtosis indicated a considerably different change pattern with respect to the sequence length. The evaluation of the multiuser interference term also exhibited similar results for both single-path and multipath scenarios. Similar results were obtained through simulations using pseudo noise sequence. A significant effect of the difference in impulsiveness on the probability of early false alarm error in a ranging scenario can be seen through simulations.
