High Code Rate Low-Density Parity-Check Codes for Optical Communication Systems
Ivan B. Djordjević, Bane V. Vasic · IEEE Photonics Technology Letters · 2004
A novel family of low-density parity-check codes based on symmetrically repeated difference systems is proposed. Codes from this family have very high code rate, girth at least six, large minimum distance, and significantly outperform conventional Reed-Solomon codes.
