Coding Theorems for Asynchronous Slepian-Wolf Coding Systems

Autor: Matsuta, Tetsunao, Uyematsu, Tomohiko

The Slepian-Wolf (SW) coding system is a source coding system with two encoders and a decoder, where these encoders independently encode source sequences from two correlated sources into codewords, and the decoder reconstructs both source sequences f

On the Distance Between the Rumor Source and Its Optimal Estimate in a Regular Tree

Autor: Matsuta, Tetsunao, Uyematsu, Tomohiko

This paper addresses the rumor source identification problem, where the goal is to find the origin node of a rumor in a network among a given set of nodes with the rumor. In this paper, we focus on a network represented by a regular tree which does n

Non-Asymptotic Bounds and a General Formula for the Rate-Distortion Region of the Successive Refinement Problem

Autor: Matsuta, Tetsunao, Uyematsu, Tomohiko

In the successive refinement problem, a fixed-length sequence emitted from an information source is encoded into two codewords by two encoders in order to give two reconstructions of the sequence. One of two reconstructions is obtained by one of two

An Information-Theoretical Analysis of the Minimum Cost to Erase Information

Autor: Matsuta, Tetsunao, Uyematsu, Tomohiko

We normally hold a lot of confidential information in hard disk drives and solid-state drives. When we want to erase such information to prevent the leakage, we have to overwrite the sequence of information with a sequence of symbols independent of t
