Abstract
A method for punctured bit estimation includes receiving a punctured codeword. The method further includes generating a reconstructed codeword using the punctured codeword and at least one punctured bit having a default logic value. The method further includes generating a syndrome vector for the reconstructed codeword. The method further includes determining, using the syndrome vector, a number of unsatisfied parity-checks for the at least one punctured bit. The method further includes determining, for the at least one punctured bit, a bit value using, at least, the number of unsatisfied parity-checks associated with the at least one punctured bit.
