Cette lettre propose une méthode de recherche rapide de porteuse, la méthode Carrier Search Step (CSSM), pour détecter rapidement la fréquence porteuse même lorsque les stations mobiles n'ont aucune connaissance des fréquences porteuses utilisées [1]. CSSM se compose de deux opérations : 1) les stations mobiles utilisent la recherche grossière à fine pour détecter le canal de synchronisation (SCH), et 2) la fréquence centrale du SCH est décalée dans la bande passante du canal afin que les stations mobiles puissent détecter le SCH dans une première étape de la recherche grossière à fine. Par rapport aux méthodes conventionnelles, CSSM peut réduire le temps de recherche de porteuse de 90 % lorsque la bande passante SCH est de 1.08 MHz et la bande passante du canal est de 5 MHz. La réduction du temps de recherche de porteuse se renforce à mesure que la bande passante du canal augmente.

Abstract: This letter proposes a fast carrier search method, the Carrier Search Step method (CSSM), to quickly detect the carrier frequency even when mobile stations have no knowledge of the carrier frequencies used [1]. CSSM consists of two operations: 1) mobile stations use the coarse-to-fine search to detect the synchronization channel (SCH), and 2) the center frequency of SCH is shifted within the channel bandwidth so that mobile stations can detect the SCH in an early step of the coarse-to-fine search. Compared with conventional methods, CSSM can reduce carrier search time by 90% when SCH bandwidth is 1.08 MHz and the channel bandwidth is 5 MHz. The reduction in carrier search time strengthens as the channel bandwidth increases.
