Dans cette lettre, le problème de l'estimation de la différence de temps d'arrivée entre les signaux reçus par deux capteurs spatialement séparés est abordé. En prenant une transformée de Fourier discrète des sorties du capteur, l'estimation du retard correspond à la recherche de la fréquence d'une sinusoïde bruyante dont l'amplitude varie dans le temps. Le prédicteur linéaire pondéré généralisé est utilisé pour estimer le retard temporel et il est montré que la précision de son estimation atteint la limite inférieure de Cramér-Rao.

Abstract: In this Letter, the problem of estimating the time-difference-of-arrival between signals received at two spatially separated sensors is addressed. By taking discrete Fourier transform of the sensor outputs, time delay estimation corresponds to finding the frequency of a noisy sinusoid with time-varying amplitude. The generalized weighted linear predictor is utilized to estimate the time delay and it is shown that its estimation accuracy attains Cramér-Rao lower bound.
