Robust Detection of Nuclear Quadrupole Resonance Signals in a Non-shielded Environment
(2011) 19th European Signal Processing Conference, EUSIPCO 2011 2011. p.2079-2083- Abstract
- Abstract in Undetermined
Nuclear quadrupole resonance (NQR) is a non-invasive
radio-frequency technique allowing for a practically unique
%ngerprint for molecules containing quadrupolar nuclei,
making the technique very promising for detection purposes.
If properly excited, these nuclei will emit electromagnetic radiation,
the frequency of which is governed mainly by where
in the molecule the nuclei are positioned. However, the resulting
NQR signals are inherently weak and are prone to
strong interference signals from the measurement environment,
making detection challenging. In this paper, we develop

cancellation and the ability to handle multiple polymorphs
in the sought substance. The usefulness of the algorithm
is motivated by comparisons using realistic simulations. (Less)
