The final codeword is a combination of the shortened code words and the condensed bits. A
representation of the final codeword is decoded by being partitioned to a selected subset …

In one embodiment, a forward substitution component performs forward substitution based
on a lower-triangular matrix and an input vector to generate an output vector. The forward …

Embodiments of the present invention are methods for break ing one or more trapping sets
in a near codeword of a failed graph-based decoder, eg, an LDPC decoder. The methods …
