A REDUCTION IN THE SEARCH SPACE OF QC-LDPC CODES WITH GIRTH 8
In this paper, we define a structure to obtain exponent matrices of girth-8 QC-LDPC codes with column weight 3. Using the difference matrices introduced by Amirzade et al., we investigate necessary and sufficient conditions which result in a Tanner graph with girth 8. Our proposed method contributes...
