Paper Abstract

In this paper an error correcting scheme for long-haul optical transmission systems based on the maximum likelihood sequence detection-Viterbi algorithm and a hard decision "Gallager B" decoding algorithm for LDPC codes is proposed. Numerical results for various LDPC codes are presented and it is shown that the proposed method provides significant coding gain with respect to the uncoded system and Viterbi equalizer only.
