INTEGRATED-INTERLEAVED LOW DENSITY PARITY CHECK (LDPC) CODES |
摘要 |
Methods and apparatus are provided for integrated-interleaved Low Density Parity Check (LDPC) coding and decoding. Integrated-interleaved LDPC encoding is performed by obtaining at least a first data element and a second data element; systematically encoding the at least first data element using a submatrix H0 of a sparse parity check matrix H1 to obtain at least a first codeword; truncating the at least first data element to obtain at least a first truncated data element; systematically encoding the at least second data element and the at least first truncated data element using the sparse parity check matrix H1 to obtain a nested codeword; and generating a second codeword based at least in part on a combination of the first codeword and the nested codeword. Integrated-interleaved LDPC decoding is also provided. |

1. A method for performing integrated-interleaved Low Density Parity Check (LDPC) encoding, comprising:
obtaining at least a first data element and a second data element; systematically encoding the at least first data element using a submatrix H0 of a sparse parity check matrix H1 to obtain at least a first codeword; truncating the at least first data element to obtain at least a first truncated data element; systematically encoding the at least second data element and the at least first truncated data element using said sparse parity check matrix H1 to obtain a nested codeword; and generating a second codeword based at least in part on a combination of the first codeword and the nested codeword. |
