Abstract:
1. An apparatus-implemented method for encoding a user word, the method comprising: (a) the apparatus separating the user word into at least first and second subwords; (b) the apparatus encoding the first subword using a first interleaving algorithm; and (c) the apparatus encoding the second subword using a second interleaving algorithm different from the first interleaving algorithm, wherein: step (b) comprises the apparatus applying the first subword to a first encoding subsystem to generate a first parity set of parity data for the first subword, wherein the first encoding subsystem comprises a first subword encoder and at least one of (i) a first subword interleaver prior to the first subword encoder and (ii) a first parity interleaver following the first subword encoder; and step (c) comprises the apparatus applying the second subword to a second encoding subsystem to generate a second parity set of parity data for the second subword, wherein the second encoding subsystem comprises a second subword encoder and at least one of (i) a second subword interleaver prior to the second subword encoder and (ii) a second parity interleaver following the second subword encoder, wherein:
