(EN) CLOCK EXTRACTION IN SYSTEMS AFFECTED BY STRONG INTERSYMBOL INTERFERENCE
(FR) EXTRACTION D'HORLOGE DANS DES SYSTÈMES AFFECTÉS PAR UNE FORTE INTERFÉRENCE ENTRE SYMBOLES
Abstract
(EN)
Timing recovery apparatus for signal reception in a data transmission system, comprises an equalizer to equalize a received signal and a phase detector connected after the timing recovery equalizer that generates a clock tone from absolute values of the received signal after equalization.
(FR)
L'invention concerne un appareil de récupération du rythme pour la réception de signaux dans un système de transmission de données. L'appareil comprend : un égaliseur pour égaliser un signal reçu ; et un détecteur de phase connecté après l'égaliseur de récupération de rythme, qui génère une tonalité d'horloge à partir de valeurs absolues du signal reçu après égalisation.
