Michael Best & Friedrich LLP
Column-layered message-passing LDPC decoder
In an illustrative example, a decoder includes a variable node unit (VNU) that includes a variable-to-check lookup table circuit configured to output a variable-to-check message corresponding to a check node. The VNU also includes a hard-decision lookup table circuit configured to output a hard decision value corresponding to a variable node. The decoder also includes a check node unit (CNU) responsive to the variable-to-check message and configured to generate an updated check-to-variable message.
