Iterative Frequency Domain Equalization for MIMO-GFDM Systems

open access: yesIEEE Access, 2018
This paper proposes a new iterative frequency domain equalization (FDE) algorithm for multiple-input multiple-output (MIMO)-frequency division multiplexing (GFDM) systems. This new FDE scheme is capable of enhancing the system fidelity by considering the

Realization of Thermal Inertia in Frequency Domain

open access: yesEntropy, 2014
To realize the lagging behavior in heat conduction observed in these two decades, this paper firstly theoretically excludes the possibility that the underlying thermal inertia is a result of the time delay in heat diffusion.

Real Wages and the Business Cycle in Germany [PDF]

open access: yes
This paper establishes stylized facts about the cyclicality of real consumer wages and real producer wages in Germany. As detrending methods we apply the deterministic trend model, the Beveridge-Nelson decomposition, the Hodrick-Prescott filter, the ...

Quantum Image Filtering in the Frequency Domain

open access: yesAdvances in Electrical and Computer Engineering, 2013
In this paper we address the emerging field of Quantum Image Processing. We investigate the use of quantum computing systems to represent and manipulate images. In particular, we consider the basic task of image filtering.

Accurate Frequency Domain Modelling of an Electric Furnace [PDF]

open access: yes, 2007
Controllers of industrial furnaces may operate differently in different temperature ranges. The controller has different parameter sets for each of these ranges. The operation of controllers is switched according to the temperature.

Time and frequency domain in the business cycle structure

open access: yesAgricultural Economics (AGRICECON), 2012
The presented paper deals with the identification of cyclical behaviour of business cycle from the time and frequency domain perspective. Herewith, methods for obtaining the growth business cycle are investigated - the first order difference, the ...

Piecewise Volterra modelling of the Duffing oscillator in the frequency domain [PDF]

open access: yes, 2010
When analysing the nonlinear Duffing oscillator, the weak nonlinearity is basically dependent on the amplitude range of the input excitation. The nonlinear differential equation models of such nonlinear oscillators, which can be transformed into the ...

Characterising spatio-temporal dynamical systems in the frequency domain [PDF]

open access: yes, 2009
In this paper a new concept, spatio-temporal generalised frequency response functions (STGFRF), is introduced for the first time to characterise spatio-temporal dynamical systems in the frequency domain.

Equivalence analysis of dielectric test methods in time domain and frequency domain

open access: yesInternational Journal of Electrical Power & Energy Systems
Wideband dielectric response is crucial for accurate assessment of insulation condition. However, time-domain measurements such as polarization and depolarization current (PDC) tests often lose high-frequency components, while frequency domain ...
