Publication number: 20210194510Abstract: 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 11/15 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.Type: ApplicationFiled: March 5, 2021Publication date: June 24, 2021Applicant: SATURN LICENSING LLCInventors: Ryoji IKEGAYA, Makiko YAMAMOTO, Yuji SHINOHARA

Patent number: 11012091Abstract: LDPC coding is executed using a check matrix of an LDPC code whose code length is 736 bits and whose code rate is 1/4, and modulation is executed using a repetition unit that has an LDPC code obtained by the LDPC coding, repeatedly arranged therein. The LDPC code includes information bits and parity bits, the check matrix includes an information matrix portion corresponding to the information bits and a parity matrix portion corresponding to the parity bits, the parity matrix portion has a stepwise structure, the information matrix portion is indicated by a check matrix initial value table, and the check matrix initial value table is a predetermined table indicating positions of elements of “1” of the information matrix portion for each eight columns. This technique is applicable to, for example, information transmission using the LDPC code.Type: GrantFiled: February 27, 2018Date of Patent: May 18, 2021Assignees: SONY CORPORATION, SONY SEMICONDUCTOR SOLUTIONS CORPORATIONInventors: Seiji Kobayashi, Masanori Sato, Nabil Loghin, Toshihiro Fujiki, Ryoji Ikegaya, Hiroyuki Kamata, Yusuke Yoneyama, Kimiya Kato, Akira Endo, Sawako Kiriyama, Hiroyuki Mita, Hideshi Motoyama, Hiroshi Aoki, Daisuke Kawakami
