Efficient Algorithms for the Bee-Identification Problem
Han Mao Kiah, Alexander Vardy, Hanwen Yao
The bee-identification problem, formally defined by Tandon, Tan and Varshney (2019), requires the receiver to identify "bees" using a set of unordered noisy measurements. In this p…
Sub-4.7 Scaling Exponent of Polar Codes
Hsin-Po Wang, Ting-Chun Lin, Alexander Vardy +1
Polar code visibly approaches channel capacity in practice and is thereby a constituent code of the 5G standard. Compared to low-density parity-check code, however, the performance…
Polar Coded Modulation via Hybrid Bit Labeling
Hanwen Yao, Jinfeng Du, Alexander Vardy
Bit-interleaved coded modulation (BICM) and multilevel coded modulation (MLC) are commonly used to combine polar codes with high order modulation. While BICM benefits from simple d…
Tropical Group Testing
Hsin-Po Wang, Ryan Gabrys, Alexander Vardy
Polymerase chain reaction (PCR) testing is the gold standard for diagnosing COVID-19. PCR amplifies the virus DNA 40 times to produce measurements of viral loads that span seven or…
Endurance-Limited Memories: Capacity and Codes
Yeow Meng Chee, Michal Horovitz, Alexander Vardy +2
\emph{Resistive memories}, such as \emph{phase change memories} and \emph{resistive random access memories} have attracted significant attention in recent years due to their better…
Computing Permanents on a Trellis
Han Mao Kiah, Alexander Vardy, Hanwen Yao
The problem of computing the permanent of a matrix has attracted interest since the work of Ryser(1963) and Valiant(1979). On the other hand, trellises were extensively studied in…
