摘要
The invention relates to an apparatus for providing at least one parity check matrix defining a spatially-coupled low density parity check, LDPC, code on the basis of a set of base matrix parameters defining a plurality of base matrices, each base matrix of the plurality of base matrices being associated with a protograph of a plurality of protographs, wherein the apparatus comprises: a processor configured to: generate on the basis of the plurality of protographs a set of candidate protographs by discarding protographs of the plurality of protographs; lift the protographs of the set of candidate protographs for generating a plurality of codes; and generate on the basis of a plurality of codes a set of candidate codes by discarding codes of the plurality of codes.
