We propose the reverse concatenated code as a forward error correction (FEC) scheme suitable for beyond 100-Gb/s optical transmission. In this scheme, BCH code is used as inner code and low-density parity-check (LDPC) code as outer code. The BCH decoder is implemented based on maximum a posteriori (MAP) decoding such as the BCJR/Ashikmin's algorithm, and an LDPC decoder is based on a min-sum-with-correction-term...
We present two hard-decision decoding schemes suitable for use in beyond 100 Gb/s optical transmission. The first scheme is based on multidimensional turbo product codes (MTPCs) with component Reed-Solomon (RS) codes. The second scheme is based on generalized low-density parity-check (GLDPC) codes with component RS codes. The proposed schemes perform comparable to recent concatenation of RS and LDPC...
We present a hard-decision decoding FEC scheme suitable for use in beyond 100 Gb/s transmission. It is based on generalized LDPC (GLDPC) codes with component RS codes. The GLPDC code of code rate 0.82 with component codes being (255,239) and (255,223) RS codes, provides the net effective coding gain of 9.67 dB at BER of 10-15.
An iterative bandwidth-efficient coded modulation scheme based on bit-interleaving, block-circulant low-density parity-check (LDPC) codes, and Many differential phase-shift keying suitable for high-speed transmission at 100 Gb/s (and above) is proposed.
