The combination of Multiple-Input Multiple-Output (MIMO) with Orthogonal Frequency Division Multiplexing (OFDM) is a promising technique for achieving high performance with very high data rates in 4G broadband wireless communications. Nevertheless, one major disadvantage of MIMO-OFDM systems lies in a prohibitively large Peak-to-Average Power Ratio (PAPR) of the transmitted signal on each antenna...
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
