Study of Barankin bound vs Cramér-Rao bound for interferometric-like array design at low SNR Open
In this paper, we address the antenna array design problem at low signal-to-noise ratio (SNR). The Cramér-Rao bound (CRB) is the most commonly used criterion to solve the array optimization problem due to its computing simplicity and tight…

Some Results on Tighter Bayesian Lower Bounds on the Mean-Square Error Open
In random parameter estimation, Bayesian lower bounds (BLBs) for the mean-square error have been noticed to not be tight in a number of cases, even when the sample size, or the signal-to-noise ratio, grow to infinity. In this paper, we stu…

A Tighter Bayesian CramÉR-rao Bound Open
It has been shown lately that any "standard" Bayesian lower bound (BLB) on the mean squared error (MSE) of the Weiss-Weinstein family (WWF) admits a "tighter" form which upper bounds the "standard" form. Applied to the Bayesian Cramer-Rao …

Caractérisation des limites fondamentales de l'erreur quadratique moyenne pour l'estimation de signaux comportant des points de rupture Open
This thesis deals with the study of estimators' performance in signal processing. The focus is the analysis of the lower bounds on the Mean Square Error (MSE) for abrupt change-point estimation. Such tools will help to characterize perform…

Prior Influence on Weiss-Weinstein Bounds for Multiple Change- Point Estimation Open
In this paper, we study the influence of the prior distribution on the Weiss-Weinstein bound (WWB) in the ubiquitous multiple change-point estimation problem. As by product, we derive a closed form expressions of the WWB for different comm…
