FPGA-Based Rate-Compatible LDPC Codes for the Next Generation of Optical Transmission Systems
IEEE Photonics Journal, 2016 In this paper, we propose a rate-compatible forward error-correcting (FEC) scheme based on low-density-parity check (LDPC) codes together with its software reconfigurable unified field-programmable gate array (FPGA) architecture.
