摘要: Discrete-time linear time-varying systems are modeled by discrete-time wavelets. The output of the unknown system is corrupted noise. model parameters estimated least-squares method applied to error. Conditions derived that provide vanishing influence noise parameter estimates. Due time-frequency selectivity wavelets, estimates can be robust narrow-band and/or impulse This robustness confirmed simulations.
