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 1):
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 4/15 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 1953 2331 2545 2623 4653 5012 5700 6458 6875 7605 7694 7881  8416 8758 9181 9555 9578 9932 10068 11479 11699  514 784 2059 2129 2386 2454 3396 5184 6624 6825 7533 7861 9116  9473 9601 10432 11011 11159 11378 11528 11598  483 1303 1735 2291 3302 3648 4222 4522 5511 6626 6804 7404 7752  7982 8108 8930 9151 9793 9876 10786 11879  1956 7572 9020 9971  13 1578 7445 8373  6805 6857 8615 11179  7983 8022 10017 11748  4939 8861 10444 11661  2278 3733 6265 10009  4494 7974 10649  8909 11030 11696  3131 9964 10480.
