Method for detecting data packets, such as ATM data cells. The preamble comprises a bit alignment word (AW) and a unique word (UW). Successively, the Hamming distances are calculated from the first detected 1-bit, over a length of AW plus UW, then from the next bit over a length of UW, and finally from the second 1-bit, again over a length of AW plug UW. The position of the first bit of the detected data packet is then calculated on the basis of the hd values thus calculated. <IMAGE> |
