Modular Arithmetic Erasure Channels and Their Multilevel Channel Polarization
Yuta Sakai, Ken-ichi Iwata, Hiroshi Fujisaki
This study proposes \emph{modular arithmetic erasure channels} (MAECs), a novel class of erasure-like channels with an input alphabet that need not be binary. This class contains t…

Asymptotic Distribution of Multilevel Channel Polarization for a Certain Class of Erasure Channels
Yuta Sakai, Ken-ichi Iwata, Hiroshi Fujisaki
This study examines multilevel channel polarization for a certain class of erasure channels that the input alphabet size is an arbitrary composite number. We derive limiting propor…

Generalizations of Fano's Inequality for Conditional Information Measures via Majorization Theory
Yuta Sakai
Fano's inequality is one of the most elementary, ubiquitous, and important tools in information theory. Using majorization theory, Fano's inequality is generalized to a broad class…
