Efficient Demodulation for Coset Codes on Lattices
Chloe Makdad, Leopold Bertholet, Mairead Cummins +2
Lattice constellations can provide significant coding and shaping gains over traditional quadrature amplitude modulations (QAMs), but have not been widely adopted due to the high i…
Two-Level Decorrelated Coded Modulation on the Lattice
Leopold Bertholet, Chloe Makdad, Stephen Mackes +2
We propose \textit{two-level decorrelated coding} (TLDC), a novel coded modulation scheme for the lattice that combines Voronoi shaping with a two-stage decoding process to a…
Optimizing Bit-Labeling of Voronoi Constellations
Carilyn Rumrill, David Muzzey, Connor Davis +2
We define a novel search method and performance metric as a technique for optimizing the bit-to-symbol map of the and root lattices in reference to bit error rate. We h…
Multilevel Coset Codes on Lattices
Leopold Bertholet, Chloe Makdad, Stephen Mackes +2
This work introduces coset Bombe codes, a novel class of multilevel coset codes that generalize polar codes to dense lattice structures. By leveraging multilevel coding with non-bi…
