Title (EN) CARRIER PHASE AMBIGUITY CORRECTION VIA DC OFFSET
(FR) CORRECTION D'AMBIGUITE DE PHASE DE PORTEUSE PAR DECALAGE EN CONTINU
Abstract: front page image
(EN)A receiver comprises a carrier tracking loop (CTL), a filter, a look-up table and a rotator. The CTL provides a baseband signal having in-phase and quadrature signal components. The filter provides a DC-offset level associated with each component to the look-up table, which, in response thereto, provides a phase adjustment signal to the rotator. The latter then rotates the baseband signal as a function of the phase adjustment signal for correcting for carrier phase ambiguity.
(FR)L'invention concerne un récepteur qui comporte une boucle de poursuite de porteuse, un filtre, une table de consultation et un rotateur. La boucle fournit un signal de bande de base à composantes de signal en phase et en quadrature. Le filtre fournit un niveau de décalage en continu associé avec chaque composante à la table de consultation, qui réagit en fournissant un signal de réglage de phase au rotateur, lequel assure la rotation du signal de bande de base en fonction du signal de réglage de phase pour la correction de l'ambiguïté de phase de porteuse.
