An ESPRIT-based parameter estimator for spectroscopic data
The pulse spin-locking sequence is a common excitation sequence for magnetic resonance and nuclear quadrupole resonance signals, with the resulting measurement data being well modeled as a train of exponentially damped sinusoidals. In this paper, we derive an ESPRIT-based estimator for such signals, together with the corre- sponding Cramér-Rao lower bound. The proposed estimator is com- putational
