  • A weight method of decoding the (23, 12, 7) Golay code using reduced table lookup

    In this paper, a weight method with using a reduced lookup table is developed to decode the three possible errors in (23, 12, 7) Golay code. The reduced lookup table consists of syndrome patterns and corresponding error patterns which only have one and two errors occurred in the message block of the received codeword. The useful proposed algorithm makes use of the properties of cyclic codes, weigh... View full abstract»

  • On efficient and reliable network coding in practical environment

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1204 KB) | HTML iconHTML

    Network coding can facilitate the communications from a sender to a set of receivers in a network by enlarging the multicast throughput. However, when applying network coding in practical network, problems such as link delay, delay jitter, and random link loss may seriously impair the network coding based multicast communications. In this paper, we carefully analyze the insufficiencies of the exis... View full abstract»

    Low-density parity-check (LDPC) codes of column weight two, also called cycle codes, can be constructed based on connected simple graphs. In this paper, efficiently encodable cycle codes and modified Repeat-Accumulate codes based on Hamiltonian graphs with large girths are devised. Specifically, the Hamiltonian property of the graphs is exploited to obtain efficient encoder structures and a concis... View full abstract»

    Parallel-input parallel-output (PIPO) structure for quasi-cyclic low-density parity-check (QC-LDPC) codes is proposed in this paper to implement a faster and more efficient QC-LDPC encoder than that based on conventional serial-input parallel-output (SIPO) or parallel-input serial-output (PISO) structure. An encoding architecture based on the proposed PIPO structure for multi-rate QC-LDPC codes em... View full abstract»

    Digital image transmission without channel coding and with turbo product codes (TPCs) as channel coding scheme over AWGN channel is studied. We propose an improved decoding algorithm for TPCs based on computing extrinsic information for partial bits. In the proposed decoding algorithm, we neglect computing extrinsic information for those bits that are reliable enough for making decoding decisions.... View full abstract»

  • Construction of quasi-cyclic LDPC codes from one-coincidence sequences

    Publication Year: 2008, Page(s):26 - 30
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1326 KB) | HTML iconHTML

    In this paper, we proposed a new method for constructing quasi-cyclic low-density parity-check (QC-LDPC) codes based on circulant permutation matrices via the one-coincidence sequences. The main advantage is that QC-LDPC codes with a variety of block lengths and rates can be easily constructed with no cycles of length four or less. Simulation results show that the proposed QC-LDPC codes perform sl... View full abstract»

  • Design of signal space diversity based on non-binary LDPC code

    In this paper, a scheme of signal space diversity based on non-binary LDPC codes is presented. Signal space diversity can provide good performance gains over fading channels with multi-dimension rotated constellation. This paper studies the extension of such schemes with a non-binary code. It is shown that non-binary LDPC-coded modulation with signal space diversity over a fading channel may lead ... View full abstract»

    In this paper, a simple decoding scheme for the quadratic residue codes that utilize extended Euclidpsilas algorithm is proposed. This decoding method is based on the property of the syndrome polynomial to obtain the error-locator polynomial. Moreover, the simulation results for comparing the new decoding method with a proposed method are given. View full abstract»

    This paper utilizes an efficient scheme which consists of a weight-counting algorithm, the combinatorial designs of the Assmus-Mattson theorem, and the weight polynomial of Gleasonpsilas theorem to determine the weight distributions of binary extended quadratic residue codes. As a consequence, the weight distribution of binary (138, 69, 22) extended quadratic residue code is given. View full abstract»

    This paper is to develop a modified algorithm for decoding the (48, 24, 12) binary quadratic residue code up to six errors. The technique in this paper uses the algebraic decoding algorithm for the (47, 24, 11) quadratic residue code offered by Truong et al. to correct up to five errors. Then, the technique of detecting a six-error is utilized. Finally, the reliability-search algorithm, proposed b... View full abstract»
