发明名称 DATA PROCESSING DEVICE AND DATA PROCESSING METHOD
摘要 The present technology relates to a data processing device and a data processing method so that an LDPC code with a good bit error rate is provided.;An LDPC encoder encodes by an LDPC code whose code length is 16200 bits and code rate is 8/15. The LDPC code includes information bits and parity bits. A parity check matrix H includes an information matrix part corresponding to the information bits of the LDPC code and a parity matrix part corresponding to the parity bits. The information matrix part of the parity check matrix H is represented by a parity check matrix initial value table that indicates a position of an element 1 of the information matrix part for each 360 columns. The present technology is applicable to a case in which LDPC encoding and LDPC decoding are performed.

主权项 1. A data processing device, comprising: an encoder, which encodes information bits into an LDPC (low density parity check) code whose code length is 16200 bits and code rate is 8/15 based on a parity check matrix of the LDPC code, the LDPC code including information bits and parity bits, the parity check matrix including an information matrix part corresponding to the information bits and a parity matrix part corresponding to the parity bits, the information matrix part being represented by a parity check matrix initial value table, and the parity check matrix initial value table being a table indicating a position of an element 1 of the information matrix part for each 360 columns as5 519 825 1871 2098 2478 2659 2820 3200 3294 3650 3804 3949 4426 4460 4503 4568 4590 4949 5219 5662 5738 5905 5911 6160 6404 6637 6708 6737 6814 7263 741281 391 1272 1633 2062 2882 3443 3503 3535 3908 4033 4163 4490 4929 5262 5399 5576 5768 5910 6331 6430 6844 6867 7201 7274 7290 7343 7350 7378 7387 7440 7554105 975 3421 3480 4120 4444 5957 5971 6119 6617 6761 6810 7067 73536 138 485 1444 1512 2615 2990 3109 5604 6435 6513 6632 6704 750720 858 1051 2539 3049 5162 5308 6158 6391 6604 6744 7071 7195 72381140 5838 6203 67486282 6466 6481 66382346 2592 5436 74872219 3897 5896 75282897 6028 70181285 1863 53243075 6005 64665 6020 75512121 3751 75074027 5488 75422 6012 70113823 5531 56871379 2262 52971882 7498 75513749 4806 72272 2074 689817 616 74829 6823 74805195 5880 7559.
