摘 要:A new predistortion linearization scheme is proposed to compensate nonlinear power amplifiers (PAs) in orthogonal frequency division multiplexing (OFDM) communication *** PA is represented by a Wiener-Hammerstein *** inverse model of the PA is constructed based on the local modeling ***,a look-up table (LUT) for constructing a predistorter (compensator) of PA is also given to simplify the proposed compensation *** effectiveness of the proposed scheme is validated by a numerical simulation.
