In this paper, a novel wireless transmission system is proposed. The system is composed of two cascaded subsystem: an inner filtered multitone (FMT) modulator with transmission over multiple antennas, and an outer Single carrier cyclic prefix (SCCP) system. The FMT modulator can efficiently avoid the inter-carrier interference, and with multiple antennas the cyclic delay diversity (CDD) can increase frequency-selectivity by inserting virtual echoes into the effective channel, and thus enhances the diversity of the system. The SCCP subsystem copes with the residual subchannel intersymbol interference. Simulation results show that the BER performance of proposed system is better than DMT-FMT system, and more suitable for the uplink Multiple-Access Channel.
