    摘要: In order to transmit a codeword that is generated based on a quasi-cyclic low-density parity-check coding scheme and consists of N cyclic blocks each consisting of Q bits, a bit permutation is applied to the bits of the codeword, a plurality of constellation blocks each consisting of G×M bits are generated, and a block permutation is applied to the constellation blocks. The bit permutation is adopted for each of N/M sections each consisting M cyclic blocks such that the constellation blocks each consist of G×M bits from M distinct cyclic blocks of the associated section. The block permutation is equivalent to writing the constellation blocks into a matrix with R rows and (Q/(k×G)) columns and reading out the constellation blocks column by column from the matrix, where R is k×(N/M), and k is a positive integer.

    摘要: The present invention relates to column-twist interleaving (24) for LDPC bit interleaved coded modulation in the DVB framework. More specifically, the present invention is directed to a row-column interleaver comprising mb columns and N/mb rows, in which N LDPC code bits are written column-by-column into the interleaver and read row-by-row from the interleaver. For each column, writing may not start at the top of the column but with an offset. The mb code bits of a row are mapped to b symbols of a 2 m QAM signal constellation. Column offset parameters are provided for LDPC codes of length 16200, b=1, and m=16 (i.e. 64 kQAM).

    摘要: A method of data encoding is disclosed. An encoder receives a set of information bits and performs an LDPC encoding operation on the set of information bits to produce a codeword based on a matched lifted LDPC code. The matched lifted LDPC code is based on a commutative lifting group and includes a number of parity bits and a submatrix to determine values of the parity bits. An order of the lifting group (Z) corresponds with a size of the lifting. A determinant of the submatrix is a polynomial of the form: ga+(g0+gL)P, where g0 is the identity element of the group, g0=gL2k, and P is an arbitrary non-zero element of a binary group ring associated to the lifting group.
