Low-density lattice codes (LDLC), introduced by Sommer, Feder and Shalvi, are a class of lattices, decoded using principles similar to low-denisty parity-check codes. This talk describes a new LDLC lattice construction based on array codes.  The main benefit is a simple description of the lattice, and a 4-cycle free parity-check matrix, which is a benefit for iterative decoding.  In addition, a modified array code version has a triangular parity-check matrix, which is amenable to quantization/shaping operations.  Numerically, the error-rate performance is equal or better than pseudo-random constructions of LDLC lattices.
