  • Storage error correction using cyclic-code based LDPC codes
    Patent number: 11929763
    Abstract: Techniques are described for joint encoding and decoding of information symbols. In one embodiment, a method for joint encoding includes, in part, obtaining a sequence of information symbols, generating a plurality of cyclic codewords each corresponding to a portion of the sequence of information symbols, jointly encoding the plurality of cyclic codewords to generate at least one combined codeword, and providing the combined codeword to a device. The at least one combined codeword may be generated through Galois Fourier Transform (GFT).
    Type: Grant
    Filed: March 29, 2021
    Date of Patent: March 12, 2024
    Assignee: WESTHOLD CORPORATION
    Inventors: Shu Lin, Khaled Ahmed Sabry Abdel-Ghaffar, Juane Li, Keke Liu
