ON THE CLASS OF ARRAY-BASED APM-LDPC CODES [PDF]
We construct an explicit class of affine permutation matrix low-density parity-check (APM-LDPC) codes based on the array parity-check matrix by using two affine maps f (x) = x-1 and g(x) = 2x-1 on Z_m, where m is an odd prime number, with girth 6 and ...

On the Minimum Distance of Generalized Spatially Coupled LDPC Codes [PDF]
Families of generalized spatially-coupled low-density parity-check (GSC-LDPC) code ensembles can be formed by terminating protograph-based generalized LDPC convolutional (GLDPCC) codes.

Binary Wyner-Ziv and CEO Problem Coding Under the Hamming Distortion Criterion [PDF]
In this paper, we present a practical encoding and decoding scheme for the binary Wyner-Ziv problem based on graph-based codes. Our proposed scheme uses low-density generator-matrix (LDGM) codes in lossy source coding part and low-density parity-check ...

Full-Length Row-Multiplier QC-LDPC Codes With Girth Eight and Short Circulant Sizes
As a special case of a quasi-cyclic (QC) low-density parity-check (LDPC) code, a full-length row-multiplier (FLRM) QC-LDPC code is described by a compact exponent matrix based on two sequences of integers.

An Iteratively Decodable Tensor Product Code with Application to Data Storage [PDF]
The error pattern correcting code (EPCC) can be constructed to provide a syndrome decoding table targeting the dominant error events of an inter-symbol interference channel at the output of the Viterbi detector.
