On the Reverse Concatenated Coded-Modulation for Ultra-High-Speed Optical Transport
Ivan B. Djordjević, Lei Xu, Ting Wang · 2011
We propose reverse concatenated code with inner BCH code and outer LDPC code. BCH decoder is based on MAP-decoding that provides high-accuracy-reliabilities for suboptimum-LDPC-decoder, leading to performance comparable to long-girth-12-LDPC codes, but with lower decoder-complexity.
