%X In this paper, a new method for time-varying ARM A model is introduced. It includes two procedures. First, using one method of signal decomposition, a signal is decomposed into some basic components; second, time-varying ARMA model is established in any of these basic components, and gets their time-frequency spectrum. This method can analyze complicated non-stationary nonlinear signal.
