DOI: 10.1016/j.ifacol.2017.08.479
Abstract: Abstract This article presents a Cramer-Rao lower bound for the discrete-time filtering problem under linear state constraints. A simple recursive algorithm is presented that extends the computation of the Cramer-Rao lower bound found in previous… read more here.

DOI: 10.1103/physrevlett.123.200503
Abstract: Only with the simultaneous estimation of multiple parameters are the quantum aspects of metrology fully revealed. This is due to the incompatibility of observables. The fundamental bound for multiparameter quantum estimation is the Holevo Cramér-Rao… read more here.

DOI: 10.1109/lsp.2022.3198335
Abstract: The Cramér-Rao bound (CRB) has been extensively used as a benchmark for estimation performance in both Bayesian and non-Bayesian frameworks. In many practical periodic parameter estimation problems, such as phase, frequency, and direction-of-arrival estimation, the… read more here.

DOI: 10.1109/taes.2017.2741298
Abstract: If a nominally L-shaped sensor-array's two legs are not exactly perpendicular, its azimuth-polar direction-of-arrival estimation would be degraded. This paper quantifies this degradation via a deterministic Cramér–Rao bound analysis of the direction-finding error variance. read more here.

DOI: 10.1109/tit.2022.3140374
Abstract: The Cramér Rao bound provides a minimum achievable variance or covariance for a parameter for a univariate or vector-valued parameter. Point processes often have parameters that are described by functions and the variance and covariance… read more here.
