Bayesian crb
Websource bearing estimation depends on θ in general, we utilize the Bayesian CRB (Van Trees 2004) as the cost function to design the optimum array. The Bayesian CRB is (Appendix 1) BCRB(L) [Eθ{FIM(L,θ)}+ Iθ]−1 (8) where Iθ − Eθ ∂2ln f(θ) ∂θ2 (9) is the Fisher information of the source bearing. The CRB of the bearing estimation for the WebIn probability theory, the chain rule and Bayes’ rule are useful tools to analyze the statistical interdependence between multi- ple random variables and to derive tractable …

WebCRB in time-varying scenarios. In this contribution, we address the open problem of de-riving an analytical expression of the off-line or also called smoothing Bayesian CRB (BCRB) for time-varying phase estimation in NDA scenarios. Explicit expressions of the BCRB and its modified version are provided in an off-line scenario. This bound helps ...

WebAbstract—This contribution considers the non-Bayesian Cramér-Rao bound (CRB) related to parameter estimation from a linearly modulated signal observed in additive white Gaussian noise. We compare the exact CRB expression for coded modula-tion with two ad hoc CRB (ACRB) expressions; the first ACRB is
