Relations between Belini-Tartara, Chazan-Zakai-Ziv, and Wax-Ziv lower bounds
Ehud Weinstein · IEEE Transactions on Information Theory · 1988
A class of lower bounds on the mean-square error in parameter estimation is presented that are based on the Belini-Tartara lower bound (1974). The Wax-Ziv lower bound (1977) is shown to be a special case in the class. These bounds often are significantly tighter than the Chazan-Zakai-Ziv lower bound (1975) when the parameter to be estimated is subject to ambiguity and threshold effects.>
