Shannon propounded a theoretical framework (collectively called information theory) that
uses mathematical tools to understand, model and analyze modern mobile wireless …

The strong converse for a coding theorem shows that the optimal asymptotic rate possible
with vanishing error cannot be improved by allowing a fixed error. Building on a method …

The problem of zero-rate multiterminal hypothesis testing is revisited from the perspective of
information-spectrum approach and finite blocklength analysis. A Neyman-Pearson-like test …

A perennial theme of information theory is to find new methods to determine the fundamental
limits of various communication systems, which potentially helps the engineers to find better …

In this paper, we consider a lossy single-user caching problem with correlated sources. We
first describe the fundamental interplay between the source correlations, the capacity of the …

We study a generalized version of Wyner's common information problem (also coined the
distributed source simulation problem). The original common information problem consists …

We derive the optimal second-order coding region and moderate deviations constant for
successive refinement source coding with a joint excess-distortion probability constraint. We …

Nonconvex optimization plays a key role in multi-user information theory and related fields,
but it is usually difficult to solve. The rate region of the Gray–Wyner source coding system (or …

Two typical fixed-length random number generation problems in information theory are
considered for general sources. One is the source resolvability problem and the other is the …

We consider the one helper source coding problem posed and investigated by Ahlswede,
Körner and Wyner. Two correlated sources are separately encoded and are sent to a …
