Analysis and Design of Staircase Codes for High Bit-Rate Fibre-Optic Communication

Abstract

Low-complexity, iterative hard-decision decoded staircase codes for hard-decision optical transport-networks (OTNs) are designed, with overheads (OH) between 6.25% and 33.3%. Extensive software simulations are performed for all code designs. Net coding gain gaps to hard-decision capacity are found to range from 0.45 dB at 6.25% OH to 1.38 dB at 33.3% OH. All code designs with
