Abstract: In an illustrative example, a method includes receiving data that includes a set of data symbols. The method further includes generating a set of parity symbols based on the set of data symbols using an erasure correcting code. The set of parity symbols includes at least a first parity symbol that is generated based on a first proper subset of the set of data symbols. The first parity symbol enables recovery of a data symbol of the first proper subset independently of a second proper subset of the set of data symbols.

Abstract: 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.
