Lower Bounds on the Lifting Degree of QC-LDPC Codes by Difference Matrices

IEEE Access, 2018
In this paper, we define two “difference matrices” which correspond to an exponent matrix. We present necessary and sufficient conditions for these difference matrices to have quasi-cyclic low-density parity-check codes (QC-LDPC) codes with

Explicit construction of girth-eight QC-LDPC codes and its application in CRT method

Tongxin xuebao, 2012
For arbitrary code lengths of the form PL(P≥3L²/4+L-1),a new family of (4,L)-regular quasi-cyclic (QC) low-density parity-check (LDPC) codes was proposed explicitly with girth ight.Employing the new code as a component code in the ...

Short Blocklength Nonbinary Raptor-Like LDPC Coding Systems Design and Simulation

IEEE Access
This paper explores an efficient rate-adaptive error correction coding scheme with a nonbinary (NB) $\mathrm {GF}(2^{q})$ extension of Raptor-like (RL) quasi-cyclic (QC) subclass of Low-Density Parity-Check (LDPC) codes.
