摘要
The present invention relates to a method and apparatus for deciding decoding order for shuffled decoding of an LDPC code. The method includes: a step of allowing a variable-check mutual information calculation unit to calculate an amount of variable-check mutual information, which is an amount of the mutual information of a message propagated from each of a plurality of check nodes to each of a plurality of variable nodes connected to each of the check nodes; and a step of allowing the variable-check mutual information calculation unit to calculate the total amount of mutual information which is the sum of the variable-check mutual information for each of the plurality of variable nodes and determining a variable node of a type having the largest total mutual information among the plurality of variable nodes in the following operation order.
