摘要： The present invention relates to a type of protograph-based LDPC codes, which are obtained from z-row-orthogonal base matrices with some additional structure constraints, such as a diagonal and/or double-diagonal structure, in order to allow a high parallelization that is a multiple of z, while having an efficient encoding or decoding. In particular, in an embodiment, a "big" base matrix is constructed from a structured square submatrix in order to have a WiMAX-like structure and a z-row-orthogonality. In another embodiment starting from a "smaller" base matrix having a part arranged in a double-diagonal shape with tail-biting one, an expansion by a factor equal to z is performed, followed by an addition of a single one-entry into the last column at a specific location, thereby obtaining a three-degree column, and followed by a row and/or column permutation in order to obtain a base matrix in a WiMAX-like structure.

摘要： The present invention relates to an apparatus and method for multi-level encoding of an input message sequence into a symbol sequence, for instance, based on polar coding. The input message comprises information bits. The apparatus is configured to divide the input message into a plurality of sub-messages, encode each of the sub-messages into a codeword, wherein a set of the sub-messages is encoded on the basis of the codewords obtained by encoding the sub-messages not in the set and a predefined function of the symbol sequence, and map the encoded sub-messages into corresponding symbols.
