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…

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…
