Abstract: The device of slot synchronisation comprises reception means (BE) for receiving a synchronisation signal containing a synchronisation code ; a local memory (LM) containing a copy of the synchronisation code ; correlation means (CMF) for performing a correlation process of the received signal with said copy of the synchronisation code, for successively delivering groups of at the most N indexed samples respectively affected with N correlation values ; selection means (SEL) for selecting among said N samples of the first group a sub-group of N1 indexed samples according to a predetermined selection criteria ; accumulation means (AD) for accumulating over G groups, energy values corresponding to the correlation values of the N1 selected indexed samples, in order to obtain N1 accumulated energy values ; detection means (DM) for acquiring the slot timing by detecting one or more maxima among the N1 accumulated energy values.
