... for Wiener systems [10] that exploits the cascade structure by jointly identifying the linear filter and the inverse nonlinearity. It uses a linear estimator  H(z) and a nonlinear estimator g( ·), ... al- gorithm. In case of the Hammerstein system, KCCA already obtains an estimate of the direct nonlinearity and the inverse linear channel. To fully identify the Hammerstein system,...
