| Description | The Ziv-Zakai bound (ZZB) provides a general mean-square error analytical baseline to evaluate time delay estimation (TDE) tech-niques for a wide range of time-bandwidth products and signal-to-noise ratios, but generally can only be numerically evaluated. The Weiss-Weinstein bound (WWB) further improves characterization of the attainable system performance, for narrowband and wide-band signals with small to moderate fractional bandwidth. Sim-ilar to the WWB, here we find a simplified closed-form ZZB for TDE with ultra-wideband (UWB) signals. The resulting simplified bound is found over disjoint segments, separated by thresholds that characterize different regions of ambiguity. The closed-form sim-plified bound can be analytically studied, and approaches both the ZZB and the TDE performance of a maximum likelihood estima-tor. In Proc. ICASSP |
