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…
Ray-Tracing vs. 3GPP TDL: Power Delay Profile Analysis in Outdoor-to-Indoor and Indoor Channels
Julia Andrusenko, Chloe Makdad
3rd Generation Partnership Project (3GPP) Technical Report (TR) 38.901 channel models (Releases 15-19) are widely used for physical-layer design and system-level evaluation in dens…
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…
An Algorithm for Ennola's Second Theorem and Counting Smooth Numbers in Practice
Chloe Makdad, Jonathan P. Sorenson
Let count the number of positive integers such that every prime divisor of is at most . Given inputs and , what is the best way to estimate …
Accelerating the Distributed Kaczmarz Algorithm by Strong Over-relaxation
Riley Borgard, Steven N. Harding, Haley Duba +4
The distributed Kaczmarz algorithm is an adaptation of the standard Kaczmarz algorithm to the situation in which data is distributed throughout a network represented by a tree. We…
