Cramér–Rao Lower Bound for Magnetic Field Localization around Elementary Structures [PDF]
SensorsThe determination of a mobile terminal’s position with high accuracy and ubiquitous coverage is still challenging. Global satellite navigation systems (GNSSs) provide sufficient accuracy in areas with a clear view to the sky. For GNSS-denied environments

Estimation of the Measurement Accuracy of Wireless Passive Resonance Sensors [PDF]
SensorsResonators are passive devices that respond to an excitation signal by oscillating at their natural frequency with exponentially decreasing amplitudes. Physical, chemical and electrical variables can modify the natural frequencies of resonators.

Localization and ambiguity resolution algorithm for time-difference fusion of three satellites based on observation filtering [PDF]
Scientific ReportsTo address the issues of low accuracy and time-difference ambiguity in the localization and tracking of multiple satellites, we have conducted a thorough study of the localization algorithm and the ambiguity resolution algorithm for the time-difference ...

Cramer-Rao lower bounds for atomic decomposition [PDF]
1999 IEEE International Conference on Acoustics, Speech, and Signal Processing. Proceedings. ICASSP99 (Cat. No.99CH36258), 1999 In a previous paper we presented a method for atomic decomposition with chirped, Gabor functions based on maximum likelihood estimation. In this paper we present the Cramer-Rao lower bounds for estimating the seven chirp parameters, and the results of a simulation showing that our sub-optimal, but computationally tractable, estimators perform well in ...

Cramer-Rao lower bounds for biased image reconstruction [PDF]
Proceedings of 36th Midwest Symposium on Circuits and Systems, 2002 Since image reconstruction and restoration are ill-posed problems, unbiased estimators often have unacceptably high variance. To reduce the variance, one introduces constraints and smoothness penalties, which yields biased estimators. This bias precludes the use of the classical Cramer-Rao (CR) lower bound for the variance of an unbiased estimator ...
