Abstract:
1. A decoding method for a low-density parity-check (LDPC) code decoder, the decoding method comprising: calculating a message of a variable node (V-node) corresponding to a current layer using log-likelihood ratio (LLR) data of a channel corresponding to a previous layer; calculating a message of a check node (C-node) of the current layer using messages of V-nodes associated with the C-node of the current layer; and calculating LLR data of a channel using the message of the V-node and the message of the C-node, wherein the calculating of the message of the V-node, the calculating of the message of the C-node, and the calculating of the LLR data of the channel, for each of a plurality of layers, are repeatedly performed.
