摘要
The paper concerns identification of the Wiener system consisting of a linear subsystem followed by a nonlinear memoryless block f (.) with no structure assumption, in particular, with no invertibility assumption. Recursive estimates are given for coefficients of the linear subsystem and for f (v) at any fixed v. All estimates given in the paper converge to the true values with probability one. A numerical example is given to justify the theoretical results.
