| Abstract: | This paper analyses the relationship between the time varying parameters of autoregressive moving average (ARMA) model of a nonstationary signal and its discrete WVD, and the relationship between time varying parameters of ARMA model and continuous WVD. WVD can be estimated from the time varying parameters of ARMA model. The theory results are verified by simulation. |
