An improved method for counting 6-cycles in low-density parity-check codes [PDF]
Since their rediscovery in the early 1990s, low-density parity-check (LDPC) codes have become the most popular error-correcting codes owing to their excellent performance. An LDPC code is a linear block code that has a sparse parity-check matrix.

Quantum LDPC Codes Based on Cocyclic Block Matrices
Motivated by a family of binary cocyclic block matrices over GF(2), we proposed a construction method to gain the stabilizer of long-length quantum error-correction codes (QECCs).

Multitype quasi-cyclic (QC) low-density parity-check (LDPC) codes are a class of protograph LDPC codes lifted cyclically from protographs with multiple edges, represented by two weight and slope matrices.

Low-Floor Tanner Codes via Hamming-Node or RSCC-Node Doping [PDF]
We study the design of structured Tanner codes with low error-rate floors on the AWGN channel. The design technique involves the “doping” of standard LDPC (proto-)graphs, by which we mean Hamming or recursive systematic convolutional (RSC) code ...

High-Throughput Multi-Frame Decoding of QC-LDPC Codes With Modified Rejection-Based Minimum Finding
The key computation in the min-sum decoding algorithm of a Low-Density Parity-Check (LDPC) is finding the first two minima and also the location of the first minimum among a set of messages passed from Variable Nodes (VNs) to Check Nodes (CNs) in a ...

Tree-structure Expectation Propagation for Decoding LDPC codes over Binary Erasure Channels [PDF]
Expectation Propagation is a generalization to Belief Propagation (BP) in two ways. First, it can be used with any exponential family distribution over the cliques in the graph.

Finite Rate QLDPC-GKP Coding Scheme that Surpasses the CSS Hamming Bound [PDF]
Quantum error correction has recently been shown to benefit greatly from specific physical encodings of the code qubits. In particular, several researchers have considered the individual code qubits being encoded with the continuous variable ...

Deriving Good LDPC Convolutional Codes from LDPC Block Codes [PDF]
Low-density parity-check (LDPC) convolutional codes are capable of achieving excellent performance with low encoding and decoding complexity. In this paper we discuss several graph-cover-based methods for deriving families of time-invariant and time ...
