| Abstract: | By using the three-level-pseudorandom-sequences with different amplitudes as input signals,
we have identified the impulse response functions of the linear part and the polynomial coefficients
of the nonlinear part of the discrete-time Wiener model of nonlinear systems. The statistic
properties of the estimated parameters and their tolerable bound are discussed in detail.
Some simulation results are included in this paper. |
