摘要

We review FEC options for short-reach optical transmissions including staircase code, concatenated staircase and Hamming code, QC-LDPC code, and LDPC convolution code. We optimize the FEC implementations employing high-throughput FPGA emulations from the aspects of decoding buffer size, fixed-point scale factor, and error floor elimination.
