FPGA-based Non-binary QC-LDPC Coding for High-Speed Coherent Optical Transmission

Not Accessible

Your library or personal account may give you access


We present a large-girth-non-binary QC-LDPC code suitable for beyond 100 Gb/s optical transmission and describe its implementation in FPGA. Great performance with Q-limit of 5.0 dB at BER of 10-10 has been found, which corresponds to NCG of 11.95 dB at 10−15.
