Efficient Removal of Noise and Interference in Multichannel Quadrupole Resonance
We present an improved multichannel detection algorithm for use in nuclear quadrupole resonance (NQR) applications. The presented method exploits spatial diversity and additional noise-only data to efficiently remove spatially and temporally correlated noise and interference components from the measured data. Numerical investigations indicate that the “cleaner” data, thus obtained, allows for impr
