    摘要： The present invention discloses a data sending method and apparatus, which resolves a problem that performance of a high coding rate LDPC code obtained in an existing puncturing manner based on a variable node degree distribution is relatively poor because in the puncturing manner, to-be-punctured parity bits that use LDPC codes cannot be effectively distinguished. The method includes: encoding, by using an LDPC code check matrix, an information bit that needs to be sent, to obtain a codeword sequence; determining a puncturing priority of each parity bit in the codeword sequence according to row destruction and/or cycle destruction, on the LDPC code check matrix, of a variable node corresponding to each parity bit; puncturing the codeword sequence according to the puncturing priority of each parity bit in the codeword sequence; and generating a bit sequence according to the punctured codeword sequence, and sending the bit sequence. In this way, performance of an obtained high coding rate LDPC code is improved.

    摘要： Disclosed are an encoder, a transmission device, and an encoding method with which the transmission amount is reduced and a deterioration in transmission efficiency is suppressed while improving reception quality when QC-LDPC or a like block encoding is used. A puncture pattern setting unit (620) searches for a puncture pattern for each integral multiple of the number of columns or for each divisor of the number of columns of a sub block matrix that forms a check matrix (H) of a QC-LDPC code, and a puncture unit (data reduction unit) (630) switches the puncture pattern for each integral multiple of the number of columns or for each divisor of the number of columns of the sub block matrix that forms the check matrix of the QC-LDPC code.

    摘要： An error coding circuit comprises a non-systematic convolutional encoder for coding an input bit stream to produce two or more groups of parity bits, an interleaver circuit for interleaving parity bits within each group of parity bits, wherein the interleaver circuit is configured to order parity bits such that odd parity bits precede even parity bits within each group of parity bits and a rate-matching circuit for outputting a selected number of the interleaved parity bits ordered by group to obtain a desired code rate.
