Coherent Optical Information Systems [PDF]

Science, 2002
Coherent optical beams are used to communicate, store, and process information in a growing number of applications. The availability of coherent laser sources is of critical importance for the realization of such optical information systems. An incoherent source randomly populates the available temporal and spatial channels of the optical system ...

COHERENT SYSTEMS ON ELLIPTIC CURVES [PDF]

International Journal of Mathematics, 2005
In this paper we consider coherent systems (E,V) on an elliptic curve which are α-stable with respect to some value of a parameter α. We show that the corresponding moduli spaces, if non-empty, are smooth and irreducible of the expected dimension. Moreover we give precise conditions for non-emptiness of the moduli spaces.

Coherent states of non-Hermitian quantum systems [PDF]

, 2006
We use the Gazeau-Klauder formalism to construct coherent states of non-Hermitian quantum systems. In particular we use this formalism to construct coherent state of a PT symmetric system. We also discuss construction of coherent states following Klauder'

Joint Carrier Frequency Offset and Phase Noise Estimation Based on Pseudo-Pilot in CO-FBMC/OQAM System

IEEE Photonics Journal, 2019
A simple method based on a designed pseudo-pilot is proposed for both carrier frequency offset (CFO) and phase noise (PN) estimation for the coherent optical offset-quadratic-amplitude modulation (QAM) based filterbank multicarrier (CO-FBMC/OQAM ...

Generalized Grassmannian Coherent States For Pseudo-Hermitian $n$ Level Systems [PDF]

, 2010
The purpose of this paper is to generalize fermionic coherent states for two-level systems described by pseudo-Hermitian Hamiltonian \cite{Trifonov}, to n-level systems.

The Residual Lifetime of Surviving Components of Coherent System under Periodical Inspections

Mathematics, 2020
In this manuscript, we gain a mixture representation for reliability function of the residual lifetime of unfailed components in a coherent system under periodical inspections, given that the number of failed components before time t1 is r(≥0), but the ...

Failure Probability Analysis of Coherent Systems using Intuitionistic Fuzzy Fault Tree Approach [PDF]

International Journal of Mathematical, Engineering and Management Sciences
In scenarios where system component failure probabilities are insufficient or imprecise, classical fault tree analysis methods often fail in providing precise assessments of system reliability and safety.

Estimation of Component Reliability in Coherent Systems With Masked Data

IEEE Access, 2019
The reliability of a coherent system of components depends on the reliability of each component and the initial statistical work should be an estimation of the reliability of each component.

Dynamics of entanglement for coherent excitonic states in a system of two coupled quantum dots and cavity QED [PDF]

, 2002
The dynamics of the entanglement for coherent excitonic states in the system of two coupled large semiconductor quantum dots ($R/a_{B}\gg 1$) mediated by a single-mode cavity field is investigated.
