Reduced-Complexity Decoding Algorithm for LDPC Codes for Practical Circuit Implementation in Optical Communications

Not Accessible

Your library or personal account may give you access

Abstract

For superior, practical decoding of LDPC based FEC, a cyclic approximated delta-minimum algorithm is proposed. Simulation shows that 3-bit soft-decision decoding provides a required Q of 6.2 dB at 10-6 BER with only 16 iterations.
