  • ATM cell detector
    Patent number: 5485461
    Abstract: 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, hd's, are calculated from the first detected l-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 plus UW. The position of the first bit of the detected data packet is then calculated on the basis of the hd values thus calculated.
