The invention relates to the fast detection of a predetermined pattern of n bits embedded in a serial bit stream (14). The n bits are adjacent or regularly distributed over the stream (as in a Time Division Multiplexed Signal), and form a unique word (16) which may in particular be used as a synchronization pattern, the detection of which allows to conclude that a synchronization status has been reached within the signal detected at a reception node. The method consists in detecting first a synchronization root, which is a subset (18) of n' consecutive bits of the unique word. A non-detection of the unique word can be evidenced very early and accordingly, a substantial amount of time can be saved in the detection, since in the average, it is not necessary to go through n comparison steps to conclude a non-detection of the unique word. |
