Abstract: This paper proposes an extrinsic information transfer (EXIT)-chart based optimization technique of LDPC ... code is also devised. In the proposed scheme, no interleaving is performed between ...

Abstract: Low density parity check (LDPC) lattices were the first family of lattices equipped with iterative decoding algorithms. We introduce quasi-cyclic LDPC (QC LDPC) lattices as a special case of ...
