| 摘要 |
The present invention relates to a data processing device and a data processing method for providing LDPC encoding at a satisfactory error rate. An LDPC encoder performs encoding by LDPC encoding by an encoding length of 16,200 bits, and an encoding rate of 12/15. The LDPC encoding includes information bits and parity bits, and the check matrix H is composed of an information matrix part corresponding to the information bits of the LDPC encoding, and a parity matrix part corresponding to the parity bits. The information matrix part of the check matrix H is represented by a check matrix initial value table representing, in each of 360 columns, the position of one element of that information matrix part. The present invention can be applied in instances of carrying out LDPC encoding and LDPC decoding. |
