This technology pertains to a data-processing device and a data processing method that make it possible to ensure good communication quality when using an LDPC code to transmit data. In group-wise interleaving, an LDPC code having a code length (N) of 16,200 bits and a code rate (r) of 12/15, 6/15, or 8/15 is interleaved on a per-bit-group basis, each bit group being 360 bits long. In group-wise deinterleaving, the interleaved LDPC code is restored to the original ordering thereof. This technology can be applied, for example, to data transmission or the like using an LDPC code. |
