Energy-efficient soft-decision LDPC FEC For long-haul optical communication
Kevin Cushon, Per Larsson-Edefors, Peter A. Andrekson · 2015
We present forward error correction systems based on a low-complexity LDPC decoding algorithm and randomly-structured LDPC codes. Simulation and ASIC synthesis results show throughput and net coding gain sufficient for long-haul applications, with greatly reduced energy consumption.
