Abstract

A novel construction method of Quasi-Cyclic Low-Density Parity-Check (QC-LDPC) code is proposed in this paper, which is based on protograph and Balanced Block Design (BIBD) in combinational mathematics. The method is to fill the base matrix of protograph with the base set elements of BIBD in accordance with certain mathematical rules. And the base matrix of protograph proposed in the paper has special double diagonal structure, which overcomes the low weight code words in general structure and achieves rapid encoding at the same time. The QC-LDPC code in this paper possesses lower
