A new transceiver system for the OFDM/OQAM modulation with Cyclic Prefix

Multi-carrier Modulation (MCM) and especially Orthogonal Frequency Division Multiplexing (OFDM) are currently used in many radio transmission standards. Among these modulations, OFDM/OQAM is an interesting alternative to OFDM. However, a simple one-tap Zero Forcing (ZF) equalization of OFDM/OQAM modulation may cause a performance floor problem, while the transmission meets a requirement of high order constellations. Therefore, more complex equalization needs to be considered, such as equalization with Interference Cancellation (EIC) technique, which has been presented to counteract the performance floor problem. In this paper, we propose a system design based on OFDM/OQAM modulation with cyclic prefix (CP) to also counteract the performance floor problem and keep simple equalization at receiver. The simulation results illustrate the efficiency of this system.
