Concatenated QC-LDPC and SPC Codes for 100 Gbps Ultra Long-Haul Optical Transmission Systems
Fiber optics communications Optical communications
2015/6/8
We propose and investigate a novel FEC coding scheme based on a concatenation of QC-LDPC with single-parity-check codes. High performance of a Q-limit of 5.8 dB with 20.5% overhead has been achieved w...
