  • Modification to Meggitt decoder for burst error correction codes
    Patent number: 8151165
    Abstract: Apparatus and methods are provided to correct burst errors from a communication channel. Embodiments may include correcting burst errors in received data using a decoder configured as a Meggitt decoder with an additional selection criterion to correct a burst error having a length larger than the code error correction capability.
    Type: Grant

  • 3-Stripes gilbert low density parity-check codes
    Patent number: 7882415
    Abstract: A method and apparatus are provided for a coding process of a communication signal. A 3-stripes parity-check matrix is generated from a parity-check matrix of a Gilbert low density parity-check code, where the parity-check matrix of the Gilbert low density parity-check code has a first stripe containing identity matrices and a second stripe containing cyclic permutation matrices. A third stripe is added to form a 3-stripes parity-check matrix, which may be applied to the coding process of information in a communication channel.

  • ITERATIVE DECODING OF CONCATENATED LOW-DENSITY PARITY-CHECK CODES
    Publication number: 20090249163
    Abstract: Techniques to perform iterative decoding of concatenated low-density parity-check codes (LDPC) are described. Iterative decoding of the concatenated code is achieved by performing T common iterations, wherein a common iteration comprises t1 decoding iterations on the inner LDPC code my means of a first decoder (340) followed by t2 decoding iterations on the outer LDPC code my means of a second decoder (350) , and wherein the two decoders exchange soft-output information.
