Abstract

In this paper, a one-step model extraction method is proposed for parameter identification of two-box nonlinear model of power amplifiers. In order to simplify the extraction complexity, the Wiener and Hammerstein-based serial structure is replaced by a parallel structure. The dynamic nonlinear filter curve and the static piecewise function formed by linear interpolating LUT entry are jointly curve-fitted to identify the parameters of the two-box model in one step. Compared with the traditional two-box model extraction method, the resultant data shows a comparable linearization performance of the proposed model in suppressing the adjacent channel error power with simplified procedures.
