Nonparametric Input Density-Free Estimation of the Nonlinearity in Wiener Systems

  title={Nonparametric Input Density-Free Estimation of the Nonlinearity in Wiener Systems},
  author={Wlodzimierz Greblicki},
  journal={IEEE Transactions on Information Theory},
The nonlinear characteristic of a Wiener system is estimated under nonparametric a priori information. The probability density of the input signal is completely unknown and can be of any form. The estimate is asymptotically biased but its bias can be made arbitrarily small. Results of computer simulations are presented.
