Statistical Signal Processing and Detector Optimization in Project 8
… I then present an original derivation of the Cramér-Rao Lower Bound of the start frequency resolution for realistic CRES signals, along with estimators yielding near-optimal performance. Finally, these improved detection and reconstruction algorithms lead into a discussion of optimal detector …

Model-based myelin water fraction mapping: analyses and improvement
… structured errors. We demonstrate through both Cramér-Rao lower bound (CRLB) analyses and Monte Carlo simulations that the three signal models are all very unstable inherently. Comparatively speaking, however, we demonstrate the theoretical advantage of the 3-exponential models over the …

Exploiting Signals of Opportunity for High-Precision PNT: Optimized Bayesian Estimation Across 5G and LEO Networks
… based on theoretically predicted performance bounds and preventing filter overconfidence. Second, a digital terrain model (DTM)-aided LEO Doppler positioning architecture is proposed to resolve the inherent altitude ambiguity of single-receiver systems and enable accurate three-dimensional …

Ultraviolet (UV) Laser Implementation, Signal Model, and Measurement Sensitivities in Filtered Rayleigh Scattering for Aerodynamic Flows
… are analyzed by evaluating and deriving the Cramér-Rao lower bound (CRLB) for each quantity. The effects of different flow conditions, Mie and geometric scattering levels, cesium vapor cell temperature, and spectral resolution are demonstrated. It is found that the best possible theoretical …

Advanced Instrumentation and Measurements Techniques for Near Surface Flows
The development of aerodynamic boundary layers on wind turbine blades is an important consideration in their performance. It can be quite challenging to replicate full scale conditions in laboratory experiments, and advanced diagnostics become valuable in providing data not available from …

Signal sampling and processing in magnetic resonance applications
… and diffusion experiments, based on the Cramér-Rao Lower Bound theory, is presented. The method is validated against pulsed field gradient NMR diffusion data of two experimental systems. In the first experimental system, the sampling pattern is optimised for the most accurate estimation …

Joint Positioning and Multipath Radio Channel Estimation and Prediction
… also includes an investigation of performance bounds that extends previously known results for the angle of arrival estimation problem and alsocontributions to joint estimation of angle of arrival and frequency error estimation. These results give an intuitive understanding of how the …
