Title
(EN) INITIAL SYNCHRONIZATION DEVICE AND METHOD
(FR) DISPOSITIF ET PROCEDE DE SYNCHRONISATION INITIALE
Abstract
(EN)
Disclosed is an initial synchronization device and method used in a mobile of a cellular telecommunication system, for identifying the frame boundary and which of a plurality of pre-defined complex valued SYNC-DL sequences is used so as to search for a cell, comprising a coefficient re-loadable match filter means, wherein said coefficient re-loadable match filter means is adapted to operate in a pipeline mode.
(FR)
L'invention concerne un dispositif et un procédé de synchronisation initiale utilisés dans un système mobile de télécommunication cellulaire, afin d'identifier la limite de trame et quelle séquence parmi une pluralité de séquences SYNC-DL à valeur complexe prédéfinie sert à rechercher une cellule, et comprenant des moyens de filtrage d'adaptation rechargeables en coefficient, ces moyens de filtrage d'adaptation rechargeables en coefficient étant conçus pour fonctionner en mode tubulaire.
