An Efficient Construction of Regular Low-Density Parity-Check Codes for Encoding

Abstract

In this paper, we propose an efficient constructions of regular LDPC codes having code rate 1/2 for encoding. The previous triangulation algorithm [4] has two disadvantages for applying ordinary regular LDPC codes. The proposed algorithm can eliminate the disadvantages of triangulation algorithm without performance degradation. We illustrate the advantages of the proposed constructions scheme and the analysis of performance of the codes constructed by proposed scheme.
