A device includes a supernode generator module, a supernode splitting module, and a control module. The supernode generator module generates S supernodes each comprising d symbol nodes, where S and d are integers greater than 1. The supernode splitting module splits each of the S supernodes into d derived symbols, wherein a total number of symbol edges of the d derived symbols is equal to a predetermined number of symbol edges of each of the S supernodes. The control module generates a quasi-cyclic irregular low density parity check (LDPC) code based on S*d derived symbols, wherein S equals the S supernodes and d equals the d derived symbols.
