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…
