Patent ID: 7283069

Claim:
A method for identifying a repeated codeword in an incoming bit stream, comprising: receiving an incoming bit stream having an expected codeword repeated a number of times; determining whether a group of incoming data bits correlates to the expected codeword by comparing each data bit from the group of incoming data bits to a corresponding bit in the expected codeword, where the number of data bits in the group equals the number of data bits which form the expected codeword and each of the data bits in the group need not match the corresponding data bit of the expected codeword; designating the group of incoming data bits as the expected codeword when the number of incoming data bits that match corresponding data bits in the expected codeword exceeds a threshold; designating the group of incoming data bits as mismatched with the expected codeword when the number of incoming data bits that match corresponding data bits in the expected codeword is less than or equal to the threshold; and determining whether the expected codeword is repeated over a sequence of incoming data bits.
