<p>A method and apparatus are disclosed that include encoding a codeword using a systematic low density parity check matrix using an encoder, the low density parity check matrix comprising a first sub-matrix associated with information symbols, a second sub-matrix having a block triangular structure associated with a first subset of parity check symbols and a third sub-matrix that is invertible and associated with a second subset of parity check symbols, the encoding performed over the second sub-matrix before the third sub-matrix.</p> |
