Multidimensional Cramér-Rao Lower Bound for Non-uniformly Sampled NMR Signals

Månsson, Anders ; Jakobsson, Andreas LU orcid and Akke, Mikael LU orcid (2014) 22nd European Signal Processing Conference - EUSIPCO 2014
Abstract
In this work, we extend recent results on the Cramé r-Rao lower

bound for multidimensional non-uniformly sampled Nuclear

Magnetic Resonance (NMR) signals. The used signal model

is more general than earlier models, allowing for the typically

present variance differences between the direct and the dif-

ferent indirect sampling dimensions. The presented bound is

verified with earlier presented 1-and R-dimensional bounds

as well as with the obtainable estimation accuracy using the

statistically efficient non-linear least squares estimator. Finally,

the usability of the presented bound is illustrated as a mea-

sure of the obtainable accuracy using three... (More)
