An approach to construct semi-random low-density parity-check (SR-LDPC) codes, is
introduced. These codes are designed with the progressive edge-growth algorithm and can …

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 …

Two new design approaches for constructing Low-Density Parity-Check (LDPC) codes are
proposed. One is used to design regular Quasi-Cyclic LDPC (QC-LDPC) codes with girth at …

We propose a scheme for the design of irregular low-density parity-check (LDPC) codes
based on Euclidian Geometry using Latin square matrices of random sequence. Our …

Low-density parity-check (LDPC) codes with scale-free (SF) symbol-node degree
distribution have been shown to provide very good error performance. When the code rate …

Low-density parity-check (LDPC) codes are normally categorized into random structure or
regular structure. In this brief, we introduce a new type of LDPC codes which is of semi …

In this paper, a method for constructing low-density parity-check (LDPC) codes of good
performance in terms of bit error rate (BER) using a computer search algorithm is presented …

An LDPC code is called ultra-sparse if its parity-check matrix has uniform column weight 2. A
class of non-binary ultra-sparse quasi-cyclic LDPC (UQ-LDPC) codes with girth 12 is …

This paper introduces different construction techniques of parity-check matrix H for irregular
Low-Density Parity-Check (LDPC) codes. The first one is the proposed Accurate Random …

In this paper, we present an approach for constructing LDPC codes with girth 8. First, we
design 3 submatrices with different shifting functions given by our schemes, then combine …
