| 摘要 |
The technology of the present invention relates to a data processing device and a data processing method that can ensure favorable communication quality in data transmission which uses low density parity check (LDPC) code. In group-wise interleaving, the code length N is 64800 bits, and LDPC code, for which the coding rate r is 9/15, is interleaved in 360 bit bit-group units. In group-wise deinterleaving, the arrangement of LDPC code after group-wise interleaving is restored to the original arrangement. The technology of the present invention can be applied, for example, to a case where data transmission using LDPC code is carried out. |
