Patent number: 8332734Abstract: A device and method for rate matching channel-encoded symbols in a data communication system. The rate matching device and method can be applied to a data communication system which uses one or both of a non-systematic code (such as a convolutional code or a linear block code) and a systematic code (such as a turbo code). In one aspect, the rate matching device includes a plurality of rate matching blocks, the number of the rate matching blocks being equal to a reciprocal of a coding rate of a channel encoder. The rate matching device can rate match the symbols encoded with a non-systematic code or the symbols encoded with a systematic code, by changing initial parameters including the number of input symbols, the number of output symbols, and the puncturing or repetition pattern determining parameters.Type: GrantFiled: May 14, 2007Date of Patent: December 11, 2012Assignee: Samsung Electronics Co., LtdInventors: Min-Goo Kim, Beong-Jo Kim, Se-Hyoung Kim, Soon-Jae Choi, Young-Hwan Lee

DPCH multiplexing apparatus and method for outer loop power control in a W-CDMA communication system
Patent number: 7609667Abstract: Disclosed is a method for transmitting a dedicated physical data channel signal over a dedicated physical data channel in the absence of transmission data to be transmitted over the dedicated physical data channel in order to properly maintain a target SIR (Signal-to-Interference Ratio) when there exists new transmission data after the absence of the transmission data in a CDMA (Code Division Multiple Access) mobile communication system. The method comprises generating a dummy bit generation request signal in the absence of the transmission data; and upon receipt of the dummy bit generation request signal, generating a dummy bit stream, and transmitting a dedicated physical data channel signal created by attaching the CRC bit stream to the dummy bit stream.Type: GrantFiled: May 12, 2006Date of Patent: October 27, 2009Assignee: Samsung Electronics Co., LtdInventors: Yong-Jun Kwak, Sung-Ho Choi, Beong-Jo Kim, Ju-Ho Lee, Sung-Oh Hwang -
Patent number: 7564821Abstract: A transmitting device including an encoder for receiving an information bit stream in a frame and outputting an information symbol, a first parity symbol, and a second parity symbol by encoding each information bit. An interleaver sequentially arranges the information symbols and the first and second parity symbols by rows in an array with an integer number of rows and an integer number of columns. The interleaver further outputs a plurality of radio frames in a stream, by reading the symbols by going down each column, starting at the leftmost column and proceeding right. Each radio frame has a predetermined size. A demultiplexer demultiplexes the radio frames received from the interleaver into streams of information, first parity symbols, and second parity symbols. A rate matcher bypasses the stream of information symbols and punctures the streams of the first and second parity symbols for rate matching.Type: GrantFiled: January 5, 2005Date of Patent: July 21, 2009Assignee: Samsung Electronics Co., Ltd.Inventors: Se-Hyoung Kim, Min-Goo Kim, Beong-Jo Kim, Soon-Jae Choi

Patent number: 7508805Abstract: The present invention relates to an apparatus and method for detecting a data rate in a turbo decoder for a mobile communication system. When a rate selector selects one data rate among a plurality of data rates, a turbo decoder repeatedly decodes an input data frame within a predetermined repetition limit number using the selected data rate and outputs the decoded data. A CRC detector performs CRC check on the decoded data and outputs the CRC check result, and a decoding state measurer measures decoding quality depending on the decoded data and outputs decoding state information. A controller then sets the repetition limit number to a predetermined minimum value, controls the repetition limit number according to the decoding state information, controls the rate selector and determines a data rate of the input data depending on the CRC check result.Type: GrantFiled: October 5, 2001Date of Patent: March 24, 2009Assignee: Samsung Electronics Co., Ltd.Inventors: Soon-Jae Choi, Min-Goo Kim, Beong-Jo Kim, Young-Hwan Lee, Nam-Yul Yu, Sang-Hyuck Ha

Patent number: 6888901Abstract: Disclosed is an apparatus for stopping iterative decoding in a turbo decoder performing iterative decoding on a received frame comprised of information bits and then outputting the iteratively decoded results. A turbo decoder sequentially outputs absolute LLR (Log Likelihood Ratio) values associated with the respective information bits of the received frame by the iterative decoding, and stops the iterative decoding in response to a stop command for the iterative decoding. A minimum LLR detector selects a minimum value M(i) among the sequentially output absolute LLR values. A controller issues a command to stop the iterative decoding, if the minimum value M(i) is larger than a first threshold determined based on a minimum value Fmin among absolute LLR values output through previous iterative decoding.Type: GrantFiled: December 20, 2001Date of Patent: May 3, 2005Assignee: Samsung Electronics Co., Ltd.Inventors: Nam-Yul Yu, Min-Goo Kim, Soon-Jae Choi, Beong-Jo Kim, Young-Hwan Lee
