Feedback does not increase the capacity of compound channels with additive noise
(Institute of Electrical and Electronics Engineers Inc., 2016)
A discrete compound channel with memory is considered, where no stationarity, ergodicity or information stability is required, and where the uncertainty set can be arbitrary. When the discrete noise is additive but otherwise ...
On the capacity of a class of MIMO channels subject to normed uncertainty
(2008)
The compound capacity of uncertain MIMO channels is considered, when the channel is modeled by a class described by an induced norm constraint. Within this framework, two types of classes are investigated, namely, additive ...
Lossless coding with generalized criteria
(2011)
This paper presents prefix codes which minimize various criteria constructed as a convex combination of maximum codeword length and average codeword length, or, a convex combination of the average of an exponential function ...
Rank-deficient solutions for optimal signaling over secure MIMO channels
(Institute of Electrical and Electronics Engineers Inc., 2014)
Capacity-achieving signaling strategies for the Gaussian wiretap MIMO channel are investigated without the degradedness assumption. In addition to known solutions, a number of new rank-deficient solutions for the optimal ...
The capacity of unstable dynamical systems-interaction of control and information transmission
(Institute of Electrical and Electronics Engineers Inc., 2017)
Feedback capacity is extended beyond classical communication channels, to stochastic dynamical systems, which may correspond to unstable control systems or unstable communication channels, subject to average cost constraints ...
Relations between information theory, robustness, and statistical mechanics of stochastic systems
(2004)
The fundamental question, which will be addressed in this talk are the relations between dissipation, which is a concept of robustness, entropy rate, which is a concept of information theory, and statistical mechanics. ...
Stochastic control over finite capacity channels: Causality and feedback
(Institute of Electrical and Electronics Engineers Inc., 2014)
Optimal communication/control analysis and design of dynamical controlled systems, when there are finite capacity communication constraints often involve information and control theoretic analysis. This paper, employees ...
Is robustness of stochastic uncertain systems related to information theory and statistical mechanics?
(2005)
Fifty years ago, when Claude Shannon was developing the Mathematical Theory of Communications, for reliable data transmission, which evolved into the subject of information theory, another discipline was developing dealing ...
Large deviations and deterministic measures of information
(Institute of Electrical and Electronics Engineers Inc., 2003)
In recent years, Large Deviations theory has found important applications in many areas of engineering and science including communication and control systems. The objective of this note is to introduce and explore connections ...
Directed information on abstract spaces: Properties and extremum problems
(2012)
This paper describes a framework in which directed information is defined on abstract spaces. The framework is employed to derive properties of directed information such as convexity, concavity, lower semicontinuity, by ...
