Abstract
a G-LDPC decoder is provided. The G-LDPC decoder includes: a generalized check node decoder configured to, in each of a plurality of iterations: group connected variable nodes into groups, the connected variable nodes being connected to an mth generalized check node among generalized check nodes; generate test patterns in each of one or more of the groups based on a first message received by the mth generalized check node from the connected variable nodes; and identify a value of a second message to be provided from the mth generalized check node to the connected variable nodes based on the test patterns; and a LDPC decoder circuitry configured to, in each of the iterations, update a value of an nth variable node, among the variable nodes, based on the second message received by the nth variable node from a generalized check node that is connected to the nth variable node.
