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 3):
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 8/15 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 32 384 430 591 1296 1976 1999 2137 2175 3638 4214 4304 4486 4662  4999 5174 5700 6969 7115 7138 7189  1788 1881 1910 2724 4504 4928 4973 5616 5686 5718 5846 6523 6893  6994 7074 7100 7277 7399 7476 7480 7537  2791 2824 2927 4196 4298 4800 4948 5361 5401 5688 5818 5862 5969  6029 6244 6645 6962 7203 7302 7454 7534  574 1461 1826 2056 2069 2387 2794 3349 3366 4951 5826 5834 5903  6640 6762 6786 6859 7043 7418 7431 7554  14 178 675 823 890 930 1209 1311 2898 4339 4600 5203 6485 6549  6970 7208 7218 7298 7454 7457 7462  4075 4188 7313 7553  5145 6018 7148 7507  3198 4858 6983 7033  3170 5126 5625 6901  2839 6093 7071 7450  11 3735 5413  2497 5400 7238  2067 5172 5714  1889 7173 7329  1795 2773 3499  2695 2944 6735  3221 4625 5897  1690 6122 6816  5013 6839 7358  1601 6849 7415  2180 7389 7543  2121 6838 7054  1948 3109 5046  272 1015 7464.
