| Abstract: | In this paper, a method of parameter identification of linear time varying systems using the desirable properties of Daubechies wavelet in time-frequency domain is presented. The core of the identification algorithm is the estimation of the parameters of the system equation from input and output measurements. First the parameters over a tiny time intervals are identified, then the evolution of the parameters over the whole duration can be estimated. |
