A Spatially-coupled Type LDPC Code with an NCG of 12 dB for Optical Transmission beyond 100 Gb/s

Abstract

We propose a novel SD-FEC employing the concatenation of a spatially-coupled type irregular LDPC code with a BCH code. Numerical simulations show an NCG of 12.0 dB at a BER of 10−15 with 25.5% redundancy.
