Robust estimation with applications to phase and envelope estimation in frequency selective wireless fading channels
(2008)
This paper derives robust niiniinax estimators for a class of uncertain models. The uncertainty is described by a relative entropy constraint between the unknown joint distribution and a fixed nominal joint distribution. ...
Control of jump linear systems over jump communication channels - Source-channel matching approach
(2007)
The control of partially observed jump linear systems over jump communication channels is investigated when the Plant State Information (I*SI) and the Channel Slate Information (CSI) are present at the transmitter and the ...
Sequential Necessary and Sufficient Conditions for optimal channel input distributions of channels with memory and feedback
(Institute of Electrical and Electronics Engineers Inc., 2016)
We derive Sequential Necessary and Sufficient Conditions (SNSC) for any channel input distribution equation to maximize directed information for channel distributions of the form equation, where Xn t {X0., Xn} and Yn t ...
Variational equalities of directed information and applications
(2013)
In this paper we introduce two variational equalities of directed information, which are analogous to those of mutual information employed in the Blahut-Arimoto Algorithm (BAA). Subsequently, we introduce nonanticipative ...
A general formula for compound channel capacity
(Institute of Electrical and Electronics Engineers Inc., 2015)
A general formula for the capacity of arbitrary compound channels, which are not necessarily ergodic, stationary or information-stable, is obtained using the information density approach. A direct (constructive) proof is ...
On optimal signaling over secure MIMO channels
(2012)
Optimal signalling over the wire-tap MIMO Gaussian channel is studied under the total transmit power constraint. A direct proof of the necessary condition of optimality (signaling on the positive directions of the difference ...
Outage probability under channel distribution uncertainty
(2011)
Outage probability of a class of block-fading (MIMO) channels is considered under channel distribution uncertainty, when the channel or its distribution are not known but the latter is known to belong to a class of ...
Capacity of Binary State Symmetric Channel with and without feedback and transmission cost
(Institute of Electrical and Electronics Engineers Inc., 2015)
We consider a unit memory channel, called Binary State Symmetric Channel (BSSC), in which the channel state is the modulo2 addition of the current channel input and the previous channel output. We derive closed form ...
Information structures of capacity achieving distribution for channels with memory and feedback
(Institute of Electrical and Electronics Engineers Inc., 2016)
The information structures of the optimal channel input distributions P[0,n] t {PAi|Ai-1,Bi-1 : i = 0,1.,n}, which correspond to the extremum problem of feedback capacity equation are identified, for any class of channel ...

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. ...
