Claim Text:
1. A method for early terminating decoding processes of a codeword coded by serial concatenated coding, comprising the steps of: A. providing a codeword, encoded by a first coding and a second coding sequentially; B. setting a maximum syndrome weight; C. decoding the second coding for the codeword by iterative calculations for syndromes; D. terminating decoding of the second coding if a syndrome weight of one iterative calculation is equal to or smaller than the maximum syndrome weight, otherwise repeating step C to step D; and E. decoding the first coding for the codeword, wherein the syndrome is a binary number which includes a plurality of “0” and “1”; and wherein the syndrome weight is an amount of “1” in the syndromes and updated after step C is completed.
