Abstract:
The present technology relates to a data processing device and a data processing method, which are capable of securing excellent communication quality in data transmission using an LDPC code. In group-wise interleave, an LDPC code in which a code length N is 16200 bits and an encoding rate r is 6/15, 8/15, or 10/15 is interleaved in units of bit groups of 360 bits. In group-wise deinterleave, a sequence of the LDPC code that has undergone the group-wise interleave is restored to an original sequence. For example, the present technology can be applied to a technique of performing data transmission using an LDPC code.

Claim (Index 2):
A data processing method comprising:\n an encoding step of performing LDPC encoding based on a parity check matrix of an LDPC code in which a code length N is 16200 bits and an encoding rate r is 6/15; a group-wise interleaving step of performing group-wise interleave of interleaving the LDPC code in units of bit groups of 360 bits; and a mapping step of mapping the LDPC code to any of 64 signal points decided in a modulation scheme in units of 6 bits, wherein in the group-wise interleave, when an (i+1)-th bit group from a head of the LDPC code is indicated by a bit group i, a sequence of bit groups 0 to 44 of the LDPC code of 16200 bits is interleaved into a sequence of bit groups 31, 38, 7, 9, 13, 21, 39, 12, 10, 1, 43, 15, 30, 0, 14, 3, 42, 34, 40, 24, 28, 35, 8, 11, 23, 4, 20, 17, 41, 19, 5, 37, 22, 32, 18, 2, 26, 44, 25, 33, 36, 27, 16, 6, and 29, the LDPC code includes an information bit and a parity bit, the parity check matrix includes an information matrix portion corresponding to the information bit and a parity matrix portion corresponding to the parity bit, the information matrix portion is represented by a parity check matrix initial value table, and the parity check matrix initial value table is a table in which a position of a 1 element of the information matrix portion is indicated for every 360 columns, and includes 27 430 519 828 1897 1943 2513 2600 2640 3310 3415 4266 5044 5100 5328 5483 5928 6204 6392 6416 6602 7019 7415 7623 8112 8485 8724 8994 9445 9667 27 174 188 631 1172 1427 1779 2217 2270 2601 2813 3196 3582 3895 3908 3948 4463 4955 5120 5809 5988 6478 6604 7096 7673 7735 7795 8925 9613 9670 27 370 617 852 910 1030 1326 1521 1606 2118 2248 2909 3214 3413 3623 3742 3752 4317 4694 5300 5687 6039 6100 6232 6491 6621 6860 7304 8542 8634 990 1753 7635 8540 933 1415 5666 8745 27 6567 8707 9216 2341 8692 9580 9615 260 1092 5839 6080 352 3750 4847 7726 4610 6580 9506 9597 2512 2974 4814 9348 1461 4021 5060 7009 1796 2883 5553 8306 1249 5422 7057 3965 6968 9422 1498 2931 5092 27 1090 6215 26 4232 6354.
