Abstract
A method and decoder for early terminating decoding processes of serial concatenated coding are disclosed. The method includes the steps of providing a codeword, encoded by a first coding and a second coding sequentially; setting a maximum syndrome weight; decoding the second coding for the codeword by iterative calculations for syndromes; terminating decoding of the second coding if a number of the iterative calculations reaches a preset number or a syndrome weight of one iterative calculation is equal to or smaller than the maximum syndrome weight, otherwise repeating the decoding step and the terminating step; and decoding the first coding for the codeword.
