  • Patent number: 10979172
    Abstract: The present technique relates to a transmission apparatus, a transmission method, a reception apparatus, and a reception method that can ensure favorable communication quality in data transmission using an LDPC code. LDPC coding is performed based on a check matrix of an LDPC code with a code length N of 69120 bits and a code rate r of 5/16, 6/16, 7/16, or 8/16. The check matrix includes a matrix A with M1 rows and K columns, where M1 represents a predetermined value, and K=N×r represents an information length of the LDPC code, a matrix B with M1 rows and M1 columns in a dual diagonal structure, a matrix Z with M1 rows and N-K-M1 columns that is a zero matrix, a matrix C with N-K-M1 rows and K+M1 columns, and a matrix D with N-K-M1 rows and N-K-M1 columns that is an identity matrix. The matrix A and the matrix C are represented by a check matrix initial value table.

  • Patent number: 10979078
    Abstract: A transmission method includes performing LDPC coding on a basis of a parity check matrix of an LDPC code having a code length N of 69120 bits and a coding rate r of 3/16, and performing group-wise interleaving in which the LDPC code is interleaved in units of bit groups of 360 bits. The transmission method further includes mapping the LDPC code to one of 16 signal points of uniform constellation (UC) in 16QAM on a 4-bit basis. In the group wise interleaving, an (i+1)th bit group from a head of the LDPC code is set as a bit group i, and a sequence of bit groups 0 to 191 of the 69120-bit LDPC code is interleaved into a sequence of bit groups.

  • Patent number: 10979080
    Abstract: The present technology relates to a data processing device and a data processing method which can ensure high communication quality in data transmission using LDPC codes. In group-wise interleaving, an LDPC code having a code length N of 64800 bits and a coding rate r of 9/15 is interleaved in a unit of a bit group of 360 bits. In group-wise deinterleaving, a sequence of bit groups of the LDPC code which has been subjected to the group-wise interleaving is returned to an original sequence. The present technology can be applied to, for example, a case in which data transmission is performed using LDPC codes.
