Abstract :
This paper presents a non-linear distortion compensator for OFDM (orthogonal frequency division multiplexing) systems. In the proposed technique, the correction is done at the receiver level by the inverse model of an amplifier. Firstly, we present OFDM technique. After this, we show the principle of our corrector. Finally, some simulations results are presented
