nuclear quadrupolar resonance autoregressive model maximum entropy method.

Abstract

The denoising method of the pulse nuclear quadrupole resonance (NQR) signals was investigated for the case of the small signal to noise ratio. The maximum entropy method of the autoregressive model was applied for the analysis of the experimental NQR data. The obtained results show the efficiency of proposed method in the conditions of the limited sampling rate for the limited time of the detection and digital signal sampling for the NQR detectors.
