New constructions of quasi-cyclic LDPC codes based on special classes of BIBD's for the AWGN and binary erasure channels

This paper presents new methods for constructing efficiently encodable quasi-cyclic LDPC codes based on special balanced incomplete block designs (BIBD's). Codes constructed perform well over both the AWGN and binary erasure channels with iterative decoding.
