Data processing device and data processing method

Abstract

In group-wise interleaving, interleaving of an LDPC code having a code length N of 64800 bits and an encoding rate r of 5/15 is performed in a unit of a bit group of 360 bits. In group-wise deinterleaving, an arrangement of the LDPC code that has undergone group-wise interleaving is returned to an original arrangement. The technology can be applied to a case of transmitting data using the LDPC code. The data processing device and data processing method can ensure excellent communication quality in data transmission using an LDPC code.

       5. A data processing method comprising:
 an encoding step of performing LDPC encoding based on a parity check matrix of an LDPC code having a code length N of 64800 bits and an encoding rate r of 5/15;   a group-wise interleaving step of performing group-wise interleaving of interleaving the LDPC code in a unit of a bit group of 360 bits; and   a mapping step of mapping the LDPC code to any one of 64 signal points decided using a modulation method in a unit of 6 bits,   wherein, in the group-wise interleaving, setting an i+1-th bit group from a head of the LDPC code as a bit group i, arrangement of bit groups 0 to 179 of the LDPC code of 64800 bits is interleaved into arrangement of bit groups   103, 116, 158, 0, 27, 73, 140, 30, 148, 36, 153, 154, 10, 174, 122, 178, 6, 106, 162, 59, 142, 112, 7, 74, 11, 51, 49, 72, 31, 65, 156, 95, 171, 105, 173, 168, 1, 155, 125, 82, 86, 161, 57, 165, 54, 26, 121, 25, 157, 93, 22, 34, 33, 39, 19, 46, 150, 141, 12, 9, 79, 118, 24, 17, 85, 117, 67, 58, 129, 160, 89, 61, 146, 77, 130, 102, 101, 137, 94, 69, 14, 133, 60, 149, 136, 16, 108, 41, 90, 28, 144, 13, 175, 114, 2, 18, 63, 68, 21, 109, 53, 123, 75, 81, 143, 169, 42, 119, 138, 104, 4, 131, 145, 8, 5, 76, 15, 88, 177, 124, 45, 97, 64, 100, 37, 132, 38, 44, 107, 35, 43, 80, 50, 91, 152, 78, 166, 55, 115, 170, 159, 147, 167, 87, 83, 29, 96, 172, 48, 98, 62, 139, 70, 164, 84, 47, 151, 134, 126, 113, 179, 110, 111, 128, 32, 52, 66, 40, 135, 176, 99, 127, 163, 3, 120, 71, 56, 92, 23, and 20,   wherein the parity check matrix includes
