“…Separating the heartbeat of mother and child is a medical example. Magnetic resonance spectroscopy often analyzes absorption spectra where different chemical components produce narrow peaks in a small frequency subband [5]. The analysis of a subband of the nonparametric periodogram just suppresses the rest of the frequencies.…”

“…Several subband methods have been proposed in the NMR literature (see e.g. [36,[40][41][42][43][44][45]). Recently, Sandgren et al [46] proposed a survey of the main subband methods and discussed their estimation performances.…”

“…It can be shown that the resulting signals can still be modeled as a combination of (a reduced number of) modes [32,44]. For notation simplicity, let x (n) be a subband signal and v be the subband image of the fullband parameter v, then the model of the subband signal is:…”

“…La signature de ces investigations est appelée signal de précession libre ou Free Induction Decay (FID) [1][2][3][4]. Pour des expériences classiques de RMN, le signal FID est analysé par des méthodes non paramétriques : FFT (Fast Fourier Transform), Périodogramme, Corrélogramme, etc., et par des méthodes paramétriques : AR (Auto-Regressive modelling), ARMA (AutoRegressive with Moving Average) [5]. Ces méthodes ont pour but d'estimer la densité spectrale de puissance du FID; plus précisément le déplacement chimiqueδ , la fréquence de résonance 0 υ et le temps de relaxation spin-spin T 2 .…”
