Information-Theoretic Meta Dynamic Programming for Signalling and Control of POMDPs
Charalambos D. Charalambous, Stelios Louka, Photios A. Stavrou
In this paper, we study the information-theoretic characterization of simultaneous signalling and control over channels modeled by partially observable Markov decision processes (P…
Signalling and Control in Nonlinear Stochastic Systems: An Information State Approach with Applications
Charalambos D. Charalambous, Stelios Louka
We consider optimal signalling and control of discrete-time nonlinear partially observable stochastic systems in state space form. In the first part of the paper, we characterize t…
A Riccati-Lyapunov Approach to Nonfeedback Capacity of MIMO Gaussian Channels Driven by Stable and Unstable Noise
Charalambos D. Charalambous, Stelios Louka
In this paper it is shown that the nonfeedback capacity of multiple-input multiple-output (MIMO) additive Gaussian noise (AGN) channels, when the noise is nonstationary and unstabl…
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…
New Formulas of Feedback Capacity for AGN Channels with Memory: A Time-Domain Sufficient Statistic Approach
Charalambos D. Charalambous, Christos Kourtellaris, Stelios Louka
In the recent paper [1] it is shown, via an application example, that the Cover and Pombra [2] "characterization of the block or transmission" feedback capacity formula, of add…
