The usual metric to assess the performance of estimators is the Cramér‐Rao Bound (CRB). However, the CRB is only accurate in the high signal‐to‐noise ratio (SNR) region. In the lower SNR regions, high estimation errors take place and the variance of the estimates approach the a ...

Using the Ziv-Zakai bound (ZZB) methodology, we develop a Bayesian mean-square error bound on time delay estimation (TDE) in convolutive random channels, and compare it with time delay estimator performance and a Cramer-Rao bound. The channel is modeled as a tapped delay line, whose taps ar...

Ziv‐Zakai Bound for Direct Position EstimationDirect position estimation (DPE) has arisen as an appealing alternative to the conventional two-step positioning (2SP) approach. The usual metric to assess the performance of estimators is the Cramer-Rao Bound (CRB). However, the CRB is only ...

Shannon's capacity and rate-distortion function, combined with the separation principle, provide tight bounds for the minimum possible distortion in joint source-channel coding. These bounds, however, are usually achievable only in the limit of a large block length. In their 1973 paper, Ziv and ...
The vector Ziv-Zakai bound is applied to the problem of estimating two-dimensional bearing with planar arrays of arbitrary geometry. The bound is calculated for square and circular arrays, and compared with the Weiss-Weinstein (1983, 1984) bound. The Ziv-Zakai bound is shown to be tighter ...
Zakai Lower Bound (ZZLB); our analytical results reveal that without large carrier-to-noise density ratio or long observation times, autocorrelation sidelobes make it impossible for an unbiased ToA estimator to attain the excellent performance promised by the simpler Cram茅r-Rao Lower Bound (CRLB)...
