  • Decoding apparatus and method based on variable error correction value
    Patent number: 8381063
    Abstract: Provided is a decoding apparatus and method based on a variable error correction value. The decoding method includes setting an initial normalized factor and a normalized factor correction value, initially updating a check node based on the initial normalized factor, and updating the check node based on a variable error correction value acquired by adding the initial normalized factor and the normalized factor correction value.
    Type: Grant
    Filed: December 15, 2008
    Date of Patent: February 19, 2013
    Assignee: Electronics and Telecommunications Research Institute
    Inventors: Euna Choi, Dae-Ig Chang, Kijoon Lee, Habong Jung
  • PREPROCESSING APPARATUS AND METHOD FOR GROUP-BASED DECODING
    Publication number: 20110200149
    Abstract: Provided are a preprocessing apparatus and a method thereof for group-based decoding. The preprocessing apparatus includes a log likelihood ratio (LLR) calculator for calculating LLRs of received signals, a signal sorter for sorting the received signals based on the calculated LLRs; and a grouping unit for grouping the sorted signals.
