ABSTRACT:
A method for hard-decision forward error correction decoding is described. A method comprises iteratively decoding a set of hard input data that has been transmitted optically, the set of hard input data having a set of information symbols, each of the set of information symbols encoded with a first forward error correction (FEC) encoding scheme and with a second FEC encoding scheme.
