TRANSMISSION METHOD AND RECEPTION DEVICE
Publication/Patent Number: US2020036394A1 Publication Date: 2020-01-30 Application Number: 16/475,557 Filing Date: 2018-02-06 Inventor: Shinohara, Yuji   Yamamoto, Makiko   Assignee: SONY CORPORATION   IPC: H03M13/27 Abstract: The present technology relates to a transmission method and a reception device capable of ensuring good communication quality in data transmission by using an LDPC code. In group-wise interleaving, an LDPC code with a code length N of 69120 bits is interleaved in units of bit groups of 360 bits. In group-wise deinterleaving, an arrangement of the LDPC code after the group-wise interleaving is returned to an original arrangement. The present technology can be applied, for example, to the case of performing data transmission by using an LDPC code or the like. The present technology relates to a transmission method and a reception device capable of ensuring good communication quality in data transmission by using an LDPC code. In group-wise interleaving, an LDPC code with a code length N of 69120 bits is interleaved in units of bit ...More ...Less

DATA PROCESSING APPARATUS AND DATA PROCESSING METHOD
Publication/Patent Number: US2020099396A1 Publication Date: 2020-03-26 Application Number: 16/696,746 Filing Date: 2019-11-26 Inventor: Shinohara, Yuji   Yamamoto, Makiko   Assignee: Saturn Licensing LLC   IPC: H03M13/11 Abstract: The present technology relates to a data processing apparatus and a data processing method which enable provision of an LDPC code that achieves good error-rate performance. 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. The present technology relates to a data processing apparatus and a data processing method which enable provision of an LDPC code that achieves good error-rate performance. An LDPC encoding unit performs encoding using an LDPC code having a code length of 64800 bits and a code ...More ...Less
