OFDM ICI Self-Cancellation Scheme Based on Five Weights

OFDM systems suffer from inter-carrier interference when they are used in mobile environment due to the appearance of Doppler frequency produced by the movement of the terminals. Recently, different schemes have been proposed in the scientific literature in order to cancel this type of interference. This paper deals with the improvement of these methods, it will be shown that our approach is able to achieve better results. Moreover, we propose to perform the signal processing only on the transmitter side allowing a reduction of the receiver complexity without any performance degradation.
