Patent number: 11627382Abstract: A transmitter for transmitting payload data and emergency information using data symbols in a single-carrier or multi-carrier broadcast system comprises a modulator configured to modulate one or more transmission symbols with signaling data for use in detecting and recovering the payload data at a receiver and to modulate one or more transmission symbols with the payload data. An emergency information receiver receives emergency information carrying information of an actual emergency. An emergency information embedder embeds emergency information into one or more transmission symbols, wherein the emergency information is embedded within a predetermined time period after its reception by using a resource used for carrying signaling data and/or payload data if no emergency information shall be transmitted. A transmission unit transmits the transmission symbols.Type: GrantFiled: November 15, 2021Date of Patent: April 11, 2023Assignee: SATURN LICENSING LLCInventors: Lothar Stadelmeier, Makiko Kan, Nabil Loghin, Daniel Schneider, Jan Zoellner, Lachlan Bruce Michael, Yuji Shinohara, Samuel Asangbeng Atungsiri, Gholam Hosein Asjadi, Matthew Paul Athol Taylor

Patent number: 7689888Abstract: A decoding apparatus and method is disclosed by which the decoder error occurrence probability is suppressed and a high decoding performance can be achieved. An ABP decoding apparatus diagonalizes a parity check matrix, updates LLR values, decodes the LLR values and then adds a decoded word obtained by the decoding to a decoded word list. The ABP decoding apparatus repeats the decoding procedure as inner repetitive decoding by a predetermined number of times. Further, as the ABP decoding apparatus successively changes initial values for priority ranks of the LLR values, it repeats the inner repetitive decoding as outer repetitive decoding by a predetermined number of times. Then, the ABP decoding apparatus selects an optimum one of the decoded words from within a decoded word list obtained by the repeated inner repetitive decoding. The invention is applied to an error correction system.Type: GrantFiled: February 1, 2006Date of Patent: March 30, 2010Assignee: Sony CorporationInventors: Makiko Kan, Toshiyuki Miyauchi

Patent number: 7607063Abstract: The present invention relates to a decoding method and a decoder, a program, a recording-and-reproducing apparatus and a method, and a reproducing apparatus and a method that are suitable for decoding encoded data encoded by using a linear code on ring R. A low-density processing unit performs parity-check-matrix low-density processing, performs linear combination for rows of a parity check matrix included in an obtained reception word, and generates a parity check matrix according to the linear-combination result, thereby reducing the density of the parity check matrix used for decoding, at step S21. Then, at step S22, an LDPC decoding unit performs decoding by using a sum product algorithm (SPA) by using the parity check matrix whose density is reduced through the processing performed at step S21. Where the processing at step S22 is finished, the LDPC decoding unit finishes decoding for the reception word. The present invention can be used for an error-correction system.Type: GrantFiled: May 28, 2004Date of Patent: October 20, 2009Assignee: Sony CorporationInventors: Atsushi Kikuchi, Masayuki Hattori, Toshiyuki Miyauchi, Kazuo Watanabe, Makiko Kan

Patent number: 7536628Abstract: The present invention provides a decoding apparatus for carrying out a decoding process on a ring-R linear code. The decoding apparatus includes coded-word holding means for acquiring a coded word with a code length reduced by omission of some symbols from the coded word and for holding the coded word; known-information addition means for attaching a reliability level of each of the symbols omitted from the coded word to reduce its code length as known symbols each having a known value to the coded word held by the coded-word holding means as known information; and repetitive decoding means for repeatedly carrying out a decoding process using belief propagation on the coded word including the known information attached to the coded word by the known-information addition means.Type: GrantFiled: February 15, 2006Date of Patent: May 19, 2009Assignee: Sony CorporationInventors: Makiko Kan, Toshiyuki Miyauchi, Kazuo Watanabe, Takashi Yokokawa

Patent number: 7318186Abstract: The present invention relates to a decoding method and a decoding apparatus in which, while the circuit scale is suppressed, the operating frequency can be suppressed within a sufficiently feasible range, and control of memory access can be performed easily, and to a program therefor. By using a transformation check matrix obtained by performing one of or both a row permutation and a column permutation on an original check matrix of LDPC (Low Density Parity Check) codes, the LDPC codes are decoded. In this case, by using, as a formation matrix, a P×P unit matrix, a quasi-unit matrix in which one or more 1s, which are elements of the unit matrix, are substituted with 0, a shift matrix in which the unit matrix or the quasi-unit matrix is cyclically shifted, a sum matrix, which is the sum of two or more of the unit matrix, the quasi-unit matrix, and the shift matrix, and a P×P 0-matrix, the transformation check matrix is represented by a combination of a plurality of the formation matrices.Type: GrantFiled: April 19, 2004Date of Patent: January 8, 2008Assignee: Sony CorporationInventors: Takahsi Yokokawa, Makiko Kan, Yasuhiro Iida, Atsushi Kikuchi
