The paper is concerned with identification algorithms of Wiener-Hammerstein nonlinear model in frequency domain. By approximately modeling the nonlinearity in the model by polynomial or spline functions, an iterative identification algorithm is proposed to obtain two linear dynamical elements as well as the nonlinear static element. A new efficient predistortion scheme for compensating nonlinear distortion of a high power amplifier is given based on the proposed nonlinear identification method.
