  Abstract: The problem of communicating over the additive white Gaussian noise (AWGN) channel with lattice codes is addressed in this paper. Theoretically, Voronoi constellations have proved to yield very powerful lattice codes when the fine lattice is AWGN-good and the coarse lattice has an optimal shaping gain. However, achieving Shannon capacity with these premises and practically implementable encoding algorithms is in general not an easy task. In this work, lattice codes called Leech constellations are proposed. They involve Construction-A lattices as fine lattices and a direct sum of multiple copies of the Leech lattice for shaping. The combination of these two ingredients allows to design finite lattice constellations of Low-Density Construction-A (LDA) lattices whose numerically measured waterfall region is situated at less than 0:8 dB from Shannon capacity. The LDA lattices embedded inside our Leech constellations are based on dual-diagonal non-binary low-density parity-check codes. A detailed explanation on how to perform encoding and demapping is given. A very appreciable feature of the proposed Leech constellations is that encoding, decoding, and demapping have all linear complexity in the blocklength.
