Abstract
Low-Density Parity-Check (LDPC) data decoding using iteration-variable accuracy is performed by segmenting a LDPC encoded data block of probability values by dividing the LDPC encoded data block into a plurality of data probability value segments and a plurality of parity probability value segments, each probability value of the LDPC encoded data block representing a likelihood between binary values, decoding the LDPC encoded data block by adjusting, according to an iteration-variable accuracy parameter, the probability values of the LDPC encoded data block based on a parity-check matrix, the parity-check matrix defining correspondence among data probability value segments and parity probability value segments, and concatenating likely binary values that satisfy the parity-check matrix associated with the probability values of each data probability value segment to form a decoded data block. The iteration-variable accuracy parameter represents a tradeoff between accuracy and computational efficiency.
