Abstract
A hard-decision (HD) forward error correcting (FEC) coded signal is decoded by a decoder to produce decoded bits using marked reliable bits of the HD-FEC coded signal and marked unreliable bits of the HD-FEC coded signal. The marked reliable and unreliable bits are computed by calculation and marking blocks based on an absolute value of log-likelihood ratios of the HD-FEC coded signal. The HD-FEC coded signal may be, for example, a staircase code coded signal or a product code coded signal.
