Apparatuses and methods for encoding and decoding of parity check codes

摘要

An encoding apparatus is provided. The encoding apparatus includes: a low density parity check (LDPC) encoder configured to generate an LDPC codeword formed of 16200 bits by performing LDPC encoding based on a parity check matrix, wherein the parity check matrix includes an information word sub-matrix and a parity sub-matrix, the information word sub-matrix being formed of a plurality of column groups each including 360 columns and being defined as a table indicating a position of one (1) present in each 360-th column.

1. An encoding apparatus for performing low density parity check (LDPC) encoding, comprising:
an LDPC encoder configured to generate an LDPC codeword formed of 16200 bits by performing the LDPC encoding on input bits based on a parity check matrix, wherein the parity check matrix includes an information word sub-matrix and a parity sub-matrix, and wherein the information word sub-matrix comprises a plurality of column groups each including 360 columns and being defined as a table indicating positions of one (1) present in each 360-th column, wherein the LDPC encoder is configured to perform the LDPC encoding using the parity check matrix defined as a following table when a code rate of an LDPC code is 7/15:Indices of rows at which 1s are positioned ini0-th column of i-th column group0432 655 893 942 1285 1427 1738 2199 2441 2565 2932 3201 41444419 4678 4963 5423 5922 6433 6564 6656 7478 7514 78921220 453 690 826 1116 1425 1488 1901 3119 3182 3568 3800 39534071 4782 5038 5555 6836 6871 7131 7609 7850 8317 84432300 454 497 930 1757 2145 2314 2372 2467 2819 3191 3256 36993984 4538 4965 5461 5742 5912 6135 6649 7636 8078 8455324 65 565 609 990 1319 1394 1465 1918 1976 2463 2987 3330 36774195 4240 4947 5372 6453 6950 7066 8412 8500 859941373 4668 5324 77775189 3930 5766 687763 2961 4207 574771108 4768 6743 710681282 2274 2750 620492279 2587 2737 6344102889 3164 7275 804011133 2734 5081 838612437 3203 7121134280 7128 849014619 4563 6206152799 6814 699116244 4212 5925171719 7657 85541853 1895 668519584 5420 6856202958 5834 8103.
