<p>A parallel concatenated coder (20) outputs a sequence of data sets in which earlier data sets contain data bits (d) and non-interleaved parity bits (p) without interleaved parity bits (q), while later data sets include the interleaved parity bits (q). Each data set is modulated as one symbol. The output format partially overcomes the delay incurred by interleaving the parity bits (q), with a substantially even distribution of data and parity bits in the sequence of data sets. The delay may be reduced further by interleaving with an index constraint.</p> |
