In this paper, we propose several precoding methods to reduce the interference caused by Faster-Than-Nyquist (FTN) signaling for Orthogonal Frequency Division Multiplexing Offset Quadrature Amplitude Modulation (OFDM/OQAM). The proposed precoders are combined with an FTN-OFDM/OQAM modulator to pre-cancel the interference at the transmitter side. An iterative receiver for each precoding scheme is also presented. With the simulations, we show that the convergence speed of the FTN-OFDM/OQAM transceiver increases with the proposed precoders.
