Construction of Girth 8 LDPC Codes based on Finite Lattice Geometries

This paper presents a novel method for constructing low density parity check (LDPC) codes with a girth of up to 8. These codes are based on the structural properties of finite lattice geometries. Results are presented which show that these codes perform well over AWGN channels with iterative decoding. These codes also have several implementation advantages, which are presented
