A Construction of High Performance Quasicyclic LDPC Codes: A Combinatoric Design Approach

Figure 1

Error-correcting performance of proposed QC-LDPC code, a QC-LDPC code based on cyclic difference families [29], a QC-LDPC code obtained from cyclic difference families [28], and a QC-LDPC code constructed based on the subsets with distinct differences between the elements [32].
