This letter proposes a new class of serially concatenated codes that can be viewed as low-
density parity-check (LDPC) codes. They are derived from multiple serially concatenated …

This paper introduces a class of Semi-Random (SR) Low-Density Parity-Check (LDPC)
codes and a class of Quasi-Cyclic (QC) LDPC codes. Both of them are derived from Multiple …

This paper presents several new construction techniques for low-density parity-check
(LDPC) and systematic repeat-accumulate (RA) codes. Based on specific classes of …

In this letter, a new rate-control scheme, called splitting, is proposed to construct low-rate
codes from highrate codes, which splits rows of parity-check matrices of repeat accumulate …

This survey guides the reader through the extensive open literature that is covering the
family of low-density parity-check LDPC codes and their rateless relatives. In doing so, we …

This letter presents a systematic and recursive method to construct good low-density parity-
check (LDPC) codes, especially those with high rate. The proposed method uses a parity …

Two classes of well-structured binary low-density parity check codes (LDPC) are described.
The first class is based on a branch of combinatorial mathematics, known as the balanced …

In this paper, we proposed a novel method for constructing quasi-cyclic low-density parity-
check (QC-LDPC) codes based on circulant permutation matrices via a simple quadratic …

This paper presents a new family of irregular repeat accumulate (IRA) low-density parity-
check (LDPC) codes with the characteristic of random-like structure, a common feature of the …

Low‐density parity‐check (LDPC) codes from affine permutation matrices, called APM‐
LDPC codes, are a class of LDPC codes whose parity‐check matrices consist of zero …
