Title (EN) REFERENCE SIGNAL DESIGN WITH ZADOFF-CHU SEQUENCES
(FR) CONCEPTION DE SIGNAL DE RÉFÉRENCE À L'AIDE DE SÉQUENCES DE ZADOFF-CHU
Abstract:
(EN) Provided are methods (400) of estimating a time delay and/or a frequency shift of a reference signal. Such methods include receiving (405) a first reference signal that is generated using a first Zadoff-Chu (ZC) sequence, receiving (410) a second reference signal that is generated using a second ZC sequence that is different than the first ZC sequence, and processing (415) the first reference signal and the second reference signal to estimate at least one of the time delay and the frequency shift of the first reference signal and/or the second reference signal.
(FR) L'invention concerne des procédés (400) d'estimation d'un retard temporel et/ou d'un décalage de fréquence d'un signal de référence. De tels procédés consistent à recevoir (405) un premier signal de référence qui est généré à l'aide d'une première séquence de Zadoff-Chu (ZC), à recevoir (410) un second signal de référence qui est généré à l'aide d'une seconde séquence ZC qui est différente de la première séquence ZC, et à traiter (415) le premier signal de référence et le second signal de référence pour estimer le retard temporel et/ou le décalage de fréquence du premier signal de référence et/ou du second signal de référence.
