Abstract
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.
