| Abstract: | In this paper, a method for estimating the parameters of continuous Hammerstein model is proposed. The Msequences of different magnitude are used as input signals herein. By means of DFT transforms, an equivalent continuous model of the linear subsystem is analysed and separated from the original. The parameters of the continuous model are directly estimated in both frequency and time domain. The simulation results show that the method is feasible and effective. |
