Modeling and identification of LPTV systems by wavelets
2004
Signal Processing
Preserved Fulltext
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. ...

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) . ...

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 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 ...
