摘要： A decoding apparatus includes a memory and a receiving unit and is adapted to decode data in units of codewords each including a parity part. The memory has a storage capacity capable of storing at least data with a length equal to the length of one codeword. The receiving unit receives, as received values, elements of a codeword in a bit-interleaved form, performs bit deinterleaving and parity permutating on the received values, and stores the resultant received values in the memory.

摘要： The present invention relates to a decoding apparatus and a decoding method, which are capable of decoding LDPC codes with a high degree of precision while preventing the circuit scale of the decoding apparatus from increasing. A computation section 1102 carries out a first computation process corresponding to three check-node processes by making use of decoding intermediate results D1101 supplied from a decoding intermediate result storage memory 1104 by way of a cyclic shift circuit 1101, and stores the result of the first computation process in a decoding intermediate result storage memory 1103. A computation section 415 carries out a second computation process corresponding to six variable-node processes by making use of decoding intermediate results D414 supplied from a decoding intermediate result storage memory 1103 by way of a cyclic shift circuit, and stores the decoding intermediate result D415 in the decoding intermediate result storage memory 1104. The present invention can be applied to, for example, a tuner for receiving (digital) satellite broadcasts.

摘要： A data processing device and a data processing method that can readily process control data having its PAPR improved. In a transmission device, a padder pads control data necessary for demodulation with zeros as dummy data, and a scrambler scrambles the padded control data (post-padding control data). A replacement unit replaces scrambled dummy data in the scrambled post-padding control data with the dummy data, and a BCH encoder and an LDPC encoder perform BCH encoding and LDPC encoding as error correction encoding on the replacement data obtained through the replacement. A shortening unit performs shortening by deleting the dummy data contained in the LDPC code and puncturing the parity bits of the LDPC code. The device can be applied in cases where control data is subjected to error correction encoding and is then transmitted, for example.
