Noise Enhancement for Weighted Sum of Type I and II Error Probabilities with Constraints

open access: yesEntropy, 2017
In this paper, the noise-enhanced detection problem is investigated for the binary hypothesis-testing. The optimal additive noise is determined according to a criterion proposed by DeGroot and Schervish (2011), which aims to minimize the weighted sum of ...

Front propagation sustained by additive noise

open access: yesPhysical Review E, 2006
The effect of noise in a motionless front between a periodic spatial state and an homogeneous one is studied. Numerical simulations show that noise induces front propagation. From the subcritical Swift-Hohenberg equation with noise, we deduce an adequate equation for the envelope and the core of the front.

Theoretical and experimental analysis of phase noise in semiconductor lasers biased below threshold

open access: yesJPhys Photonics
We report a theoretical and experimental study of phase noise in semiconductor lasers when the bias current is below the threshold value. The theoretical study is performed by using two types of rate equations, with additive and multiplicative noise ...

THE DETERMINISTIC CHAOS OSCILLATOR BASED ON A FIELD-EFFECT TRANSISTOR STRUCTURE WITH NEGATIVE RESISTANCE FOR TELECOMMUNICATIONS SYSTEMS

open access: yesInformation and Telecommunication Sciences, 2016
Background. Application of deterministic chaos oscillators in telecommunication systems requires knowledge about their dynamical properties. Mathematical models and phase portraits of such generators are well known.

Detection of multiplicative noise in stationary random processes using second- and higher order statistics [PDF]

open access: yes, 2000
This paper addresses the problem of detecting the presence of colored multiplicative noise, when the information process can be modeled as a parametric ARMA process.

Cellular Uplink Impairments in Vehicular Repeater Deployments

open access: yesIEEE Open Journal of Vehicular Technology
Vehicular repeater systems improve the mobile coverage inside railroad cars by amplifying the signals received by a pick-up antenna on the roof and distributing the amplified signals inside the car.

Influence of noise shape on excitation kinetics of impurity doped quantum dots

open access: yesManufacturing Review, 2014
Noise influences the functioning of nanomaterials and optoelectronic materials to a significant extent. We investigate the excitation kinetics of a repulsive impurity doped quantum dot initiated by the application of external white noise with special ...

Competitive Prediction Under Additive Noise

open access: yesIEEE Transactions on Signal Processing, 2009
In this correspondence, we consider sequential prediction of a real-valued individual signal from its past noisy samples, under square error loss. We refrain from making any stochastic assumptions on the generation of the underlying desired signal and try to achieve uniformly good performance for any deterministic and arbitrary individual signal.
