Abstract

Dispersive selected mapping (DSLM) is a method to reduce the peak-to-average power ratio (PAPR) of filter bank multicarrier offset quadrature Modulation (FBMC/OQAM) system, but this method needs to transmit extra bits of side information (SI), so caused a waste of spectrum resources . Based on DSLM, a novel dispersive selected mapping method without side information (New-DSLM) is proposed in this paper. New-DSLM redefines the phase sequence and insert extension factor with a modulus greater than 1, then recover the transmitted symbol at the receiver by calculating the difference energy between the extension factor and adjacent positions. NEW-DSLM does not need to transmit side information, thereby avoiding the waste of spectrum resources. The simulation results show that the proposed method can effectively reduce PAPR and the bit error rate (BER) is not high.
