Charalambos D. Charalambous, Christos Kourtellaris, Themistoklis Charalambous
In \cite{butman1976} the linear coding scheme is applied, , , , with ,…
On the Cover and Pombra Gaussian Feedback Capacity: Complete Sequential Characterizations via a Sufficient Statistic
Charalambos D. Charalambous, Christos Kourtellaris, Stelios Louka
The main objective of this paper is to derive a new sequential characterization of the Cover and Pombra \cite{cover-pombra1989} characterization of the finite block or transmis…
Feedback Capacity Formulas of AGN Channels Driven by Nonstationary Autoregressive Moving Average Noise
Stelios Louka, Christos Kourtellaris, Charalambos D. Charalambous
In this paper we derive closed-form formulas of feedback capacity and nonfeedback achievable rates, for Additive Gaussian Noise (AGN) channels driven by nonstationary autoregressiv…
Joint Nonanticipative Rate Distortion Function for a Tuple of Random Processes with Individual Fidelity Criteria
Charalambos D. Charalambous, Evagoras Stylianou
The joint nonanticipative rate distortion function (NRDF) for a tuple of random processes with individual fidelity criteria is considered. Structural properties of optimal test cha…
Joint Rate Distortion Function of a Tuple of Correlated Multivariate Gaussian Sources with Individual Fidelity Criteria
Evagoras Stylianou, Charalambos D. Charalambous, Themistoklis Charalambous
In this paper we analyze the joint rate distortion function (RDF), for a tuple of correlated sources taking values in abstract alphabet spaces (i.e., continuous) subject to two ind…
Structural Properties of Optimal Test Channels for Distributed Source Coding with Decoder Side Information for Multivariate Gaussian Sources with Square-Error Fidelity
Michail Gkagkos, Charalambos D. Charalambous
This paper focuses on the structural properties of test channels, of Wyner's operational information rate distortion function (RDF), , of a tuple of multivariate…
