Method of Constructing a Parity-Check Matrix for Using Message-Passing Algorithm to Decode the Repeat-Accumulate Type of Modulation and Coding Schemes |
| 摘要 |
A method in a network node comprises generating a parity-check matrix for decoding a transmission scheme. The transmission scheme comprises a repetition code, an interleaver, and a modulation having a memory property. The parity-check matrix comprises a function of: a differentiator matrix, the differentiator matrix comprising an inverse of an accumulator matrix; a deinterleaver matrix, the deinterleaver matrix comprising an inverse of an interleaver matrix, the interleaver matrix comprising a square unitary permutation matrix for introducing randomness; and a repetition decoder matrix. |
