Methods, apparatus, and systems are provided for error correction of a communication signal. A generalized multiple threshold scheme for iteratively decoding a received codeword may include generating a bit reliability based on a channel output reliability and an updated bit reliability from a previous decoding iteration, where the bit reliability is updated using a scaling factor and a comparison with a threshold. The threshold may have a plurality of threshold values during the iterative decoding.
