Abstract
In this paper, we present a time varying autoregressive (TVAR) representation for the amplitude frequency modulated (AM-FM) signal. In the proposed method the TVAR coefficients are estimated by the nonlinear energy (NLE) operator. It is demonstrated that the proposed technique based on NLE has certain distinct advantages over the conventional method employing basis functions (BF).
