Abstract: A method of decoding a low density parity check (LDPC) code, includes dividing a parity check matrix of the LDPC code, into a plurality of sub blocks. The method further includes, for each of a plurality of decoding iterations, performing a node operation of each of target sub blocks among the plurality of sub blocks, the target sub blocks corresponding to a present decoding iteration among the plurality of decoding iterations, in a decoding schedule, estimating a reliability of each of the target sub blocks, based on a result of the node operation of each of the target sub blocks, and adjusting the decoding schedule, based on the reliability of each of the target sub blocks.
