Abstract

We propose a class of moderate-length nonbinary low-density parity-check (LDPC) codes for long-haul high-speed optical transmission systems. In particular, we present an LDPC code with 12.59% redundancy that achieves a 9.9-dB coding gain at a bit-error rate of 10^-10. A similar coding gain is obtained for a long nonbinary LDPC code with a redundancy of only 6.7%.
