Abstract
An LDPC encoding unit performs encoding using an LDPC code having a code length of 64800 bits and a code rate of 18/30, 19/30, 20/30, 21/30, 22/30, or 23/30. The LDPC code includes information bits and parity bits, and a parity check matrix H is composed of an information matrix portion corresponding to the information bits of the LDPC code, and a parity matrix portion corresponding to the parity bits. The information matrix portion of the parity check matrix H is represented by a parity check matrix initial value table that shows positions of elements of 1 in the information matrix portion in units of 360 columns. The present technology may be applied to LDPC encoding and LDPC decoding.

Claim
1. A data processing apparatus comprising:
an encoding unit configured to encode information bits into an LDPC (Low Density Parity Check) code having a code length of 64800 bits and a code rate of 18/30 on the basis of a parity check matrix of the LDPC code, wherein the LDPC code includes information bits and parity bits, the parity check matrix includes an information matrix portion corresponding to the information bits and a parity matrix portion corresponding to the parity bits, 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 showing positions of elements of 1 in the information matrix portion in units of 360 columns, including 113 1557 3316 5680 6241 10407 13404 13947 14040 14353 15522 15698 16079 17363 19374 19543 20530 22833 24339 271 1361 6236 7006 7307 7333 12768 15441 15568 17923 18341 20321 21502 22023 23938 25351 25590 25876 25910 73 605 872 4008 6279 7653 10346 10799 12482 12935 13604 15909 16526 19782 20506 22804 23629 24859 25600 1445 1690 4304 4851 8919 9176 9252 13783 16076 16675 17274 18806 18882 20819 21958 22451 23869 23999 24177 1290 2337 5661 6371 8996 10102 10941 11360 12242 14918 16808 20571 23374 24046 25045 25060 25662 25783 25913 28 42 1926 3421 3503 8558 9453 10168 15820 17473 19571 19685 22790 23336 23367 23890 24061 25657 25680 0 1709 4041 4932 5968 7123 8430 9564 10596 11026 14761 19484 20762 20858 23803 24016 24795 25853 25863 29 1625 6500 6609 16831 18517 18568 18738 19387 20159 20544 21603 21941 24137 24269 24416 24803 25154 25395 55 66 871 3700 11426 13221 15001 16367 17601 18380 22796 23488 23938 25476 25635 25678 25807 25857 25872 1 19 5958 8548 8860 11489 16845 18450 18469 19496 20190 23173 25262 25566 25668 25679 25858 25888 25915 7520 7690 8855 9183 14654 16695 17121 17854 18083 18428 19633 20470 20736 21720 22335 23273 25083 25293 25403 48 58 410 1299 3786 10668 18523 18963 20864 22106 22308 23033 23107 23128 23990 24286 24409 24595 25802 12 51 3894 6539 8276 10885 11644 12777 13427 14039 15954 17078 19053 20537 22863 24521 25087 25463 25838 3509 8748 9581 11509 15884 16230 17583 19264 20900 21001 21310 22547 22756 22959 24768 24814 25594 25626 25880 21 29 69 1448 2386 4601 6626 6667 10242 13141 13852 14137 18640 19951 22449 23454 24431 25512 25814 18 53 7890 9934 10063 16728 19040 19809 20825 21522 21800 23582 24556 25031 25547 25562 25733 25789 25906 4096 4582 5766 5894 6517 10027 12182 13247 15207 17041 18958 20133 20503 22228 24332 24613 25689 25855 25883 0 25 819 5539 7076 7536 7695 9532 13668 15051 17683 19665 20253 21996 24136 24890 25758 25784 25807 34 40 44 4215 6076 7427 7965 8777 11017 15593 19542 22202 22973 23397 23423 24418 24873 25107 25644 1595 6216 22850 25439 1562 15172 19517 22362 7508 12879 24324 24496 6298 15819 16757 18721 11173 15175 19966 21195 59 13505 16941 23793 2267 4830 12023 20587 8827 9278 13072 16664 14419 17463 23398 25348 6112 16534 20423 22698 493 8914 21103 24799 6896 12761 13206 25873 2 1380 12322 21701 11600 21306 25753 25790 8421 13076 14271 15401 9630 14112 19017 20955 212 13932 21781 25824 5961 9110 16654 19636 58 5434 9936 12770 6575 11433 19798 2731 7338 20926 14253 18463 25404 21791 24805 25869 2 11646 15850 6075 8586 23819 18435 22093 24852 2103 2368 11704 10925 17402 18232 9062 25061 25674 18497 20853 23404 18606 19364 19551 7 1022 25543 6744 15481 25868 9081 17305 25164 8 23701 25883 9680 19955 22848 56 4564 19121 5595 15086 25892 3174 17127 23183 19397 19817 20275 12561 24571 25825 7111 9889 25865 19104 20189 21851 549 9686 25548 6586 20325 25906 3224 20710 21637 641 15215 25754 13484 23729 25818 2043 7493 24246 16860 25230 25768 22047 24200 24902 9391 18040 19499 7855 24336 25069 23834 25570 25852 1977 8800 25756 6671 21772 25859 3279 6710 24444 24099 25117 25820 5553 12306 25915 48 11107 23907 10832 11974 25773 2223 17905 25484 16782 17135 20446 475 2861 3457 16218 22449 24362 11716 22200 25897 8315 15009 22633 13 20480 25852 12352 18658 25687 3681 14794 23703 30 24531 25846 4103 22077 24107 23837 25622 25812 3627 13387 25839 908 5367 19388 0 6894 25795 20322 23546 25181 8178 25260 25437 2449 13244 22565 31 18928 22741 1312 5134 14838 6085 13937 24220 66 14633 25670 47 22512 25472 8867 24704 25279 6742 21623 22745 147 9948 24178 8522 24261 24307 19202 22406 24609.
