Capacity of gaussian channels with noise uncertainty
(2004)In this paper the problem of defining, and computing the capacity of a communication channel when the statistic of an additive noise is not fully known, is addressed. The communication channel is specified as a continuous ...

Discrete-time risk-sensitive filters with non-Gaussian initial conditions and their ergodic properties
(IEEE, 1999)In this paper, we study asymptotic stability properties of risk-sensitive filters with respect to their initial conditions. In particular, we consider a linear time-invariant systems with initial conditions that are not ...

Experimental determination of the absolute temperature modulation in photothermal microscopy of Y1Ba2Cu3O7 crystals
(1997)We present a technique to experimentally determine the value of the temperature perturbation ST in photothermal microscopy. Knowledge of δT is necessary for proper analysis of the differential optical reflectivity (∂R/∂T) ...

First passage risk-sensitive criterion for stochastic evolutions
(1995)The purpose of this paper is to investigate in an infinite dimensional space, the first passage problem with a risk-sensitive performance criterion, and to illustrate the asymptotic behavior of the associated value function, ...

Necessary conditions for partially observed diffusions
(IEEE, 1993)We present a new approach to deriving necessary conditions for stochastic partially observed control problems when the control enters the drift coefficient, and correlation between signal and observation noise is allowed. ...

New finite-dimensional risk-sensitive filters: Small-noise limits
(IEEE, 1997)This paper is concerned with continuous-time nonlinear risk-sensitive filters. It is shown that for large classes of nonlinearities entering both the dynamics and measurements, these filters are finite-dimensional, ...

On the role of feedback in the design of perfectly reconstructing equalizers
(2007)In this paper we consider the transmission of discrete data via a communication channel that is subject to (additive) noise with a known upper bound on its magnitude but otherwise completely unrestricted behavior. We are ...

Optimal preprocessing strategies for perfect reconstruction of binary signals under power-constrained transmission
(2004)In this paper we further explore our deterministic worst-case framework for perfect reconstruction of discrete data transmissions through dispersive communication channels. Specifically, we are concerned with perfect ...

Robust capacity of white Gaussian noise channels with uncertainty
(2004)This paper concerns the problem of defining, and computing the channel capacity of a continuous time additive white Gaussian noise channel when the true frequency response of the channel is not completely known to the ...

The role of information state and adjoint in relating nonlinear output feedback risk-sensitive control and dynamic games
(1997)This paper employs logarithmic transformations to establish relations between continuous-time nonlinear partially observable risk-sensitive control problems and analogous output feedback dynamic games. The first logarithmic ...

A Simple Information Theoretic Proof of the Maximum Entropy Property of Some Gaussian Random Fields
(1994)A well known result of Burg and Kiinsch identifies a Gaussian Markov random field with autocovariances specified on a finite part L of the n-dimensional integer lattice, as the random field with maximum entropy among all ...

Stochastic models for short-term multipath fading channels: chi-square and Ornstein-Uhlenbeck processes
(IEEE, 1999)This paper discusses the use of stochastic differential equations to model signal envelope variations over areas, which are subject to short-term fading effects. The short-term fading effects are modeled using Ornstein-Uhlenbeck ...

A Systems Approach to Channel Equalization
(2003)In this paper we present a control theoretic frame-work for channel equalization. Channel equalization methods are used to mitigate the effects of inter-symbol interference (ISI). Traditional methods, maximize the signal ...

Wavelet analysis of motor unit action potentials
(IEEE, 1996)In this study the usefulness of the wavelet transforms (WT) Daubechies with 4 and 20 coefficients, Chui, and Battle-Lemarie in analyzing MUAPs recorded from normal subjects and subjects suffering with motor neuron disease ...
