Abstract
Techniques related to improving the decoding performance of codewords, such as LDPC codewords, are described. In an example, the error-correction capability of a decoding layer is improved, where the improvements may include lowering the error floor. To do so, higher order information is used in the decoding. Higher order information refers to, during the decoding of a variable node that is in error, using information that is not limited to the variable node and check nodes connected thereto, but includes information related to variable nodes that are also in error and connected to the variable node via satisfied check nodes and related to unsatisfied check nodes connected to such variable nodes.
