Capacity Achieving Distributions and Separation Principle for Feedback Gaussian Channels With Memory: the LQG Theory of Directed Information
Charalambous, Charalambos D.; Kourtellaris, Christos K.; Loyka, Sergey (2018)A method is developed to realize optimal channel input conditional distributions, which maximize the finite transmission feedback information (FTFI) capacity, often called $n$ -block length feedback capacity, by information ...

Control-Coding Capacity of Decision Models Driven by Correlated Noise and Gaussian Application Examples
Charalambous, Charalambos D.; Kourtellaris, Christos K.; Loyka, Sergey (2018)We characterize the n -finite time feedback information (FTFI) control-coding capacity of decision models (DMs) driven by correlated noise. Under information stability the per unit limit, called control-coding (CC) capacity ...

Finite Blocklength Analysis of the Multiple Access Relay Channel with Batch-and-Forward Strategy
Kourtellaris, Christos K.; Psomas, Constantinos; Krikidis, Ioannis (2019)This work provides a comprehensive framework regarding the analysis of the Multiple Access Relay Channel (MARC) with Time Division Multiple Access (TDMA) scheduling, subject to finite blocklength constraints. In particular, ...

A General Coding Scheme for Signaling Gaussian Processes Over Gaussian Decision Models
Charalambous, Charalambos D.; Kourtellaris, Christos K.; Charalambous, Themistoklis (IEEE, 2018)In this paper, we transform the n-finite transmission feedback information (FTFI) capacity of unstable Gaussian decision models with memory on past outputs, subject to an average cost constraint of quadratic form derived ...

Information Structures for Feedback Capacity of Channels With Memory and Transmission Cost: Stochastic Optimal Control and Variational Equalities
Kourtellaris, Christos K.; Charalambous, Charalambos D. (2018)Stochastic optimal control theory and a variational equality of directed information are applied, to develop a methodology to identify the information structures of optimal channel input conditional distributions, which ...

Nonanticipative information theory
Kourtellaris, Christos K. (Πανεπιστήμιο Κύπρου, Πολυτεχνική Σχολή / University of Cyprus, Faculty of Engineering, 2014-06)Η κλασσική θεωρία πληροφορίας χρησιμοποιεί την αμοιβαία πληροφορία για να ορίσει τη χωρητικότητα των καναλιών και τη συμπίεση των πηγών πληροφορίας. Για κανάλια και πηγές χωρίς μνήμη και ανατροφοδότηση, το μέτρο αυτό μπορεί ...
