This technology pertains to a device and method for processing data 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 64800 bits and a code rate r of 7/15, 9/15, 11/15, or 13/15 is interleaved on a bit-group unit basis, each bit group comprising 360 bits. In group-wise deinterleaving, the interleaved LDPC code is restored to the original ordering thereof. This invention can be applied when carrying out data transmission using LDPC coding for example. |
