Construction of non-binary LDPC codes: A matrix-theoretic approach
Juane Li, Keke Liu, Shu Lin, Khaled Abdel-Ghaffar · 2014
This paper presents a matrix-theoretic approach to the construction of non-binary LDPC codes. Two algebraic methods for constructing non-binary LDPC codes are presented. The proposed construction methods have several ingredients including base matrix, matrix-dispersion, masking and replacement. By proper choice and combination of these ingredients, non-binary LDPC codes with good performance can be constructed.
