Abstract:
The present technology relates to a data processing apparatus and a data processing method that are able to provide an LDPC code with a good error rate. An LDPC encoder performs coding by an LDPC code having a code length of 16200 bits and a code rate of 12/15. The LDPC code includes an information bit and a parity bit, and a parity check matrix H is configured with an information matrix portion corresponding to the information bit of the LDPC code and a parity matrix portion corresponding to the parity bit. An information matrix portion of the parity check matrix H is represented by a parity check matrix initial value table representing a position of an element of 1 in the information matrix portion at an interval of 360 columns. The present technology may be applied to a case of performing an LDPC coding and an LDPC decoding.

Claim (Index 1):
A data processing apparatus comprising:\n a coding unit that encodes an information bit into an LDPC code having a code length of 16200 bits and a code rate of 12/15, based on a parity check matrix of a low density parity check (LDPC) code, wherein the LDPC code includes an information bit and a parity bit, wherein the parity check matrix includes an information matrix portion corresponding to the information bit and a parity matrix portion corresponding to the parity bit, wherein the information matrix portion is represented by a parity check matrix initial value table, and wherein the parity check matrix initial value table is a table representing positions of elements of 1 in the information matrix portion at an interval of 360 columns, and is 3 394 1014 1214 1361 1477 1534 1660 1856 2745 2987 2991 3124 3155 59 136 528 781 803 928 1293 1489 1944 2041 2200 2613 2690 2847 155 245 311 621 1114 1269 1281 1783 1995 2047 2672 2803 2885 3014 79 870 974 1326 1449 1531 2077 2317 2467 2627 2811 3083 3101 3132 4 582 660 902 1048 1482 1697 1744 1928 2628 2699 2728 3045 3104 175 395 429 1027 1061 1068 1154 1168 1175 2147 2359 2376 2613 2682 1388 2241 3118 3148 143 506 2067 3148 1594 2217 2705 398 988 2551 1149 2588 2654 678 2844 3115 1508 1547 1954 1199 1267 1710 2589 3163 3207 1 2583 2974 2766 2897 3166 929 1823 2742 1113 3007 3239 1753 2478 3127 0 509 1811 1672 2646 2984 965 1462 3230 3 1077 2917 1183 1316 1662 968 1593 3239 64 1996 2226 1442 2058 3181 513 973 1058 1263 3185 3229 681 1394 3017 419 2853 3217 3 2404 3175 2417 2792 2854 1879 2940 3235 647 1704 3060.
