The filter bank multicarrier with offset quadrature amplitude modulation (FBMC-OQAM) has attracted great interest in recent years for its low Adjacent Channel Leakage Ratio (ACLR). However, the problem of high peak-to-average power ratio (PAPR) has negative impact on the energy efficiency of the FBMC system. In this paper, we investigate PAPR reduction of FBMC-OQAM signals based on partial transmit sequence techniques (PTS). It has been shown that a trellis-based PTS scheme with multi-block joint optimization (MBJO) is superior to most schemes based on symbol-by-symbol PTS approach. However, the complexity of this scheme is undesirable in most cases. Several suboptimal solutions have been introduced in order to reduce the complexity at the expense of significant performance loss. To achieve a better complexity-performance tradeoff, we propose an improved scheme to approach the performance of trellis-based PTS with a lower complexity. The simulation results confirm that the proposed scheme effectively reduces the PAPR of FBMC-OQAM signals.
