- W2803500521 abstract "As an alternative waveforms of the fifth generation mobile communication system (5G), filter bank multicarrier with offset quadrature amplitude modulation (FBMC-OQAM) is a powerful signal processing method that allows data transmission with a maximum bandwidth efficiency, but it still has a high peak-to-average power ratio (PAPR). In this paper, a novel algorithm for PAPR reduction is proposed by analyzing the essential cause of PAPR produced in FBMC-OQAM system. The proposed algorithm is divided into two parts: Hadamard Transform (HT) and randomly assigning prototype filters (RAPF). The essence of FBMC-OQAM system with high PAPR has two reasons: the first one is affected by the aperiodic correlation of send signals, which can be improved by HT; the second one is affected by consistent phase-frequency characteristic, and it can be improved through RAPF. Different prototype filters are randomly assigned to subcarriers in order to adjust the phase congruency. Theoretical analysis and simulation results show that the PAPR of FBMC-OQAM system can be reduced significantly by this algorithm." @default.
