In the recent fifth generation (5G) research, filter bank multi-carrier (FBMC) technique is one of the competitive substitutes to orthogonal frequency division multiplexing (OFDM). The conventional FBMC schemes, such as FBMC staggered-modulated multitone (FBMC-SMT) and frequency spreading FBMC (FS-FBMC), have the intrinsic time-domain interference which is caused by the overlap of symbols and depend on offset quadrature amplitude modulation (OQAM). In order to overcome the two drawbacks, a non-overlapping QAM-FBMC scheme is proposed based on the FBMC-SMT and analyzed in this paper. Moreover, the non-overlapping QAM-FBMC scheme not only discards cyclic prefix (CP) as other FBMC schemes, but also shortens the duration length of symbol waveforms compared with that of FS-FBMC. Therefore, its spectrum efficiency (SE) outperforms other multi-carrier systems. Simulation results indicate that non-overlapping QAM-FBMC scheme indeed improves the SE and obtains almost the same bit error rate performance as that of the FBMC-SMT as well as OFDM in multi-path fading channel.
