A generalized low-density parity check code (GLDPC) is a low-density parity check code in which the constraint nodes of the code graph are block codes, rather than single parity checks. In this paper, we study GLDPC codes which have BCH or Reed-Solom

In this paper, a general framework which enables to compare previously proposed block decoding approaches for the fast correlation attack is developed. All attacks are based on decoding using a set of parity check sums of an underlying linear code. T

We describe simple iterative decoders for low-density parity-check codes based on Euclidean geometries, suitable for practical very-large-scale-integration implementation in applications requiring very fast decoders. The decoders are based on shuffle

In this correspondence, iteration-1 of bit flipping decoding based on a set of nonorthogonal check sums is analyzed for both regular and irregular models. In particular, the tradeoff between the Hamming weight (and overlapping) of the check sums and

In this paper, the mean field (MF) and mixed mean field (MMF) algorithms for decoding low-density parity-check (LDPC) codes are considered. The MF principle is well established in statistical physics and artificial intelligence. Instead of using a si

In this letter, a general orthogonal-modulation model to develop new modulations and to identify some widely used modulation schemes is proposed. Based on this general framework, an optimum scheme for non-Gaussian channels under a given set of constr

In this correspondence, a new method for improving hard-decision bit-flipping decoding of low-density parity-check (LDPC) codes is presented. Bits with a number of unsatisfied check sums larger than a predetermined threshold are flipped with a probab

The main reference of this paper is the sphere-packing bound of 1967 (SP67) derived by Shannon, Gallager, and Berlekamp. It offers a lower bound on the decoding error probability over a very large variety of channels. If it has failed so far to provi

In this correspondence, the construction of low-density parity-check (LDPC) codes from circulant permutation matrices is investigated. It is shown that such codes cannot have a Tanner graph representation with girth larger than 12, and a relatively m

The statistical approach proposed by D. Agrawal and A. Vardy (see IEEE Trans. Inform. Theory, vol.46, pp.60-83, Jan. 2000) to evaluate the error performance of the generalized minimum distance (GMD) decoding is extended to other reliability based dec
