Abstract

La présente invention se rapporte à un procédé de détermination de la synchronisation d'un signal reçu dans un récepteur de système de positionnement global et émis par un satellite de système de positionnement global. Ledit procédé consiste à effectuer un codage par transformation dudit signal reçu de manière à transformer ledit signal en transformant ses coefficients du domaine temporel en coefficients du domaine fréquentiel, à sélectionner parmi les coefficients du domaine fréquentiel ceux qui apportent une contribution sensiblement nulle à l'énergie du signal, et à dériver desdits coefficients sélectionnés une indication d'estimation du bruit intra-bande.
