Center node: "multilevel constructions coding packing and geometric uniformity"
  Abstract: Lattice and special nonlattice multilevel constellations constructed from binary codes, such as Construction C, have relevant applications in mathematics (sphere packing) and communication problems (multi-stage decoding and efficient vector quantization). In this work, we explore some properties of Construction C, in particular its geometric uniformity. We then propose a new multilevel construction, motivated by bit interleaved coded modulation, that we call Construction $C^\star$. We explore the geometric uniformity and minimum distance properties of Construction $C^\star,$ and discuss its potential superior packing efficiency with respect to Construction C.
