The present invention provides a method to achieve frame synchronization from a received data sequence before the carrier phase and frequency offset recovery for any MPSK modulated signals on the basis of maximum likelihood theory. Two over-head configurations are considered in developing the frame synchronization algorithms (S25). One overhead configuration consists of a unique word (3a) followed by a preamble (3b), and the other consists of unique word (7) only. After the frame synchronization is achieved, the time position is known. The data-aided algorithms for carrier phase and frequency-offsets estimation (S29) are derived.

L'invention concerne un procédé permettant d'exécuter une synchronisation de trame à partir d'une séquence de données reçue avant la récupération du décalage en fréquence et en phase porteuses pour des signaux MPSK modulés quelconques en fonction de la théorie de probabilité maximale. On prend en compte deux configurations de surcharge pour l'élaboration d'algorithmes de synchronisation de trame (S25). Une configuration de surcharge consiste en un mot unique (3a) suivi d'un préambule (3b) et l'autre configuration consiste seulement en un mot unique (7). Après l'exécution de la synchronisation de trame, la position temporelle est connue. Des algorithmes s'appuyant sur des données destinés à une estimation des décalages en fréquence et en phase porteuses (S29) sont dérivés.
