ABSTRACT:
A method is provided for detecting a synchronization word in frames of serially transmitted data. The synchronization word consists of l synchronization bits, which are transmitted one bit per frame at a known position in each frame. The method comprises the steps of: storing each incoming bit in a memory organized as groups of words, each having at least l bits, so that each group of words contains bits from a same position in consecutive frames; rotating each group of words; comparing the group of words, at each rotation, to the synchronization word.
