Abstract: An operating method of an error correction decoder includes receiving data, setting initial log-likelihood values of variable nodes, and decoding the received data by updating a log-likelihood value of a selected variable node by use of a minimum value and a minimum candidate value associated with the selected variable node. The minimum value indicates a minimum value of absolute values of log-likelihood values of first variable nodes sharing a check node with the selected variable node and including the selected variable node. The minimum candidate value indicates one from among absolute values of log-likelihood values of second variable nodes that has the smallest value greater than the minimum value. The second variable nodes are selected later than one from among the first variable nodes corresponding to the minimum value.

Abstract: An operating method of an error correction decoder includes receiving data, setting initial log-likelihood values of variable nodes, and decoding the received data by updating a log-likelihood value of a selected variable node by use of a minimum value and a minimum candidate value associated with the selected variable node. The minimum value indicates a minimum value of absolute values of log-likelihood values of first variable nodes sharing a check node with the selected variable node and including the selected variable node. The minimum candidate value indicates one, greater than the minimum value and smallest, from among absolute values of log-likelihood values of second variable nodes that are selected later than one, corresponding to the minimum value, from among the first variable nodes.

Abstract translation: 纠错解码器的操作方法包括：接收数据，设置变量节点的初始对数似然值，以及通过使用最小值和最小候选值更新所选择的变量节点的对数似然值来解码接收到的数据 与所选择的变量节点相关联。 最小值表示共享具有所选变量节点并且包括所选变量节点的校验节点的第一变量节点的对数似然值的绝对值的最小值。 最小候选值表示从第一可变节点之中选择的比最小值对应的第二变量节点的对数似然值的绝对值中的大于最小值和最小值的值。
