Le domaine de l’imagerie a toujours fait l’objet de curiosité, que ce soit pour enregistrer une scène, ou voir au-delà des limites de l’oeil humain grâce aux détecteurs infrarouges. Ces deux types d’imagerie sont réalisés avec différe

Traditional synchronization techniques are usually challenged by Faster-than-Nyquist (FTN) signals which discard orthogonal pulses to the advantage of an increased spectral efficiency. In this paper, we studied data-aided timing estimation in FTN sce
