Modeling and identification of LPTV systems by wavelets

Y. Dorfan, A. Feuer, B. Porat
2004 Signal Processing  
The wavelets model will be shown to be particularly suitable for adaptive identification of LPTV systems. It offers a compromise between time-and frequency-based algorithms.  ...  We propose a novel model for discrete Linear Periodic Time Varying (LPTV) systems using wavelets. The new model is compared with the 'raised model', which is commonly used for modeling LPTV systems.  ...  Fig. 5 . 5 The WAT and WST structures. Fig. 6 . 6 The new wavelet model for LPTV systems. Fig. 7 . 7 Sub-domains of LPTV models.  ...

The steady-state impedance operator of a linear periodically time-varying one-port network and its determination

Radosław Kłosiński
2009 International Journal of Applied Mathematics and Computer Science  
This description makes it possible to quantitatively assess LPTV system input and output harmonics aliasing.  ...  The paper also presents the derivation and the proof of convergence of an iteration scheme for the identification of circular parametric operators.  ...  Discrete time LPTV systems can also be modeled by discrete time wavelets. It makes the system identification robust to narrow-band or impulse noise (Doroslovacki et al., 1998) .  ...

Frequency domain, parametric estimation of the evolution of the time-varying dynamics of periodically time-varying systems from noisy input–output observations

E. Louarroudi, J. Lataire, R. Pintelon, P. Janssens, J. Swevers
2014 Mechanical systems and signal processing  
Furthermore, it is assumed that the system under consideration can be excited by a broad-band periodic signal with a user-defined amplitude spectrum (i.e. multisine), and that the periodicity of the excitation  ...  This paper presents a parametric, frequency domain identification method for modeling continuous-(discrete-) time, periodically time-varying systems from input-output measurements.  ...  This work also benefits from K.U.Leuven-BOF PFV/10/002 Centerof-Excellence Optimization in Engineering (OPTEC), and the IWT-SBO 80032 (LECOPRO) project of the Institute for the Promotion of Innovation  ...

2-Norm-Based Iterative Design of Filterbank Transceivers: A Control Perspective

Yang Shi, Tongwen Chen
2008 Journal of Control Science and Engineering  
This paper considers design of filterbank-based transceivers. A composite error criterion is proposed to capture all the three traditional distortions.  ...  Incorporating noise attenuation and filter bandlimiting properties into this error criterion, an optimal design procedure is developed and applied to a transceiver design example, yielding an FIR transceiver  ...  This research was supported by the Natural Sciences and Engineering Research Council of Canada and the Canada Foundation of Innovation.  ...

Cyclostationarity: Half a century of research

William A. Gardner, Antonio Napolitano, Luigi Paura
2006 Signal Processing  
In the latter, signals are modelled as single functions of time and statistical functions are defined through infinite-time averages instead of ensemble averages.  ...  In the former, which is the classical one, signals are modelled as realizations of stochastic processes.  ...  The identification of LTI systems based on noisy input/output measurements is considered in [2. 5, 2.8,9.11,9.12,9.36,9.37 Blind LTI-system identification and equalization By specializing (3.84)  ...
