Abstract:
A data processing device and a data processing method capable of improving resistance to error of data. An LDPC encoder encodes by an LDPC code whose code length is 16200 bits and code rate is 4/15, 7/15, or 8/15. A parity check matrix of the LDPC code is composed by arrangement of an element of an information matrix determined by a parity check matrix initial value table indicating a position of the element of the information matrix corresponding to an information length corresponding to the code length and the code rate for each 360 columns of the parity check matrix with a period of 360 columns in a column direction. The parity check matrix initial value table is for digital broadcasting for a mobile terminal, for example. This technology may be applied to a case in which LDPC encoding and LDPC decoding are performed.

Claim (Index 2):
A data processing device, comprising:\n an encoder, which encodes information bits into a cord word whose code length is 16200 bits and code rate is 7/15 based on a parity check matrix of an LDPC (low density parity check) code, wherein the LDPC code encoded by the encoder includes an information bit and a parity bit, the parity check matrix includes an information matrix part corresponding to the information bit and a parity matrix part corresponding to the parity bit, the information matrix part is represented by a parity check matrix initial value table, and the parity check matrix initial value table is a table indicating a position of an element 1 of the information matrix part for each 360 columns as 3 137 314 327 983 1597 2028 3043 3217 4109 6020 6178 6535 6560  7146 7180 7408 7790 7893 8123 8313 8526 8616 8638  356 1197 1208 1839 1903 2712 3088 3537 4091 4301 4919 5068 6025  6195 6324 6378 6686 6829 7558 7745 8042 8382 8587 8602  18 187 1115 1417 1463 2300 2328 3502 3805 4677 4827 5551 5968  6394 6412 6753 7169 7524 7695 7976 8069 8118 8522 8582  714 2713 2726 2964 3055 3220 3334 3459 5557 5765 5841 6290 6419  6573 6856 7786 7937 8156 8286 8327 8384 8448 8539 8559  3452 7935 8092 8623  56 1955 3000 8242  1809 4094 7991 8489  2220 6455 7849 8548  1006 2576 3247 6976  2177 6048 7795 8295  1413 2595 7446 8594  2101 3714 7541 8531  10 5961 7484  3144 4636 5282  5708 5875 8390  3322 5223 7975  197 4653 8283  598 5393 8624  906 7249 7542  1223 2148 8195  976 2001 5005.
