Abstract

The letter presents a new technique for constructing regular and irregular quasi-cyclic (QC) low density parity check (LDPC) codes with girth 6. Codes are designed by the combinatorial concept, in which subsets representing circulant matrices are originated from a particular subset. Conducted simulations confirm that implemented codes have low error floor, while they provide good performance in the waterfall region.
