Abstract:
1. A computer-implemented method for generating a transmission word for a set of user-data values, the method comprising: (a) adding, by a padding-value inserter, a set of padding values to the set of user-data values to form a dataword; (b) interleaving, by an interleaver, the dataword; (c) encoding, by an encoder, the interleaved dataword to generate a codeword comprising the set of user-data values and a set of parity values; and (d) generating, by a transmission-word generator, the transmission word comprising the set of user-data values and the set of parity values, wherein: the transmission word is smaller than the codeword; the interleaving of step (b) is local/global interleaving; and step (b) comprises: (b1) the interleaver interleaving on a local unit basis, a first subset of dataword values to generate a first group of two or more global units; (b2) the interleaver interleaving on the local unit basis, a second subset of dataword values to generate a second group of two or more global units; and (b3) the interleaver interleaving on a global unit basis, greater than the local unit basis, at least the global units of the first and second groups to generate the interleaved dataword.
