LDPC SELECTIVE DECODING SCHEDULING USING A COST FUNCTION

摘要

A cost function is obtained. For each of a plurality of groups of check nodes associated with low-density parity-check (LDPC) encoded data, the cost function is evaluated using information associated with a variable node and/or information associated with a check node. One of the groups of check nodes is selecting based at least in part on the evaluated cost functions. Error correction decoding related processing is performed on the selected group of check nodes.
