“…By selecting the optimal LRC parameters, the authors achieved a compromise between the best outcomes in reducing PAPR and BER. The authors suggest the weibull companding (WC) in [21] which is new non-linear companding that consists of transforming the amplitude of the FBMC signal into a Weibull transformation, where the simulation results show the effective trade-off between BER and PAPR reduction. Using the companding with other techniques to further improve the PAPR and BER performances is also proposed in the literature.…”

Multi-carrier modulation (MCM) is one of the fundamental components of beyond 5G (B5G) and 6G that meets the many requirements of contemporary use cases. Filter bank multi-carrier with offset quadrature amplitude modulation (FBCM/OQAM) is one of the most promising modulation that offers many benefits to the next generation. However, like all MCM modulations, it shows a high peak signal in the time domain, which causes in-band (IB) and out-of-band (OOB) distortions in the amplifier output signal. The present paper suggests that an FBMC/OQAM system with multi-input multi-output (MIMO) employs a new hybridization that combines repeated clipping filtering (RCF) with several companding techniques, including A-Law, Mu-Law, tangente rooting (tanhR), logarithmic rooting (logR), cos and rooting companding (RTC). The combination of RCF and Mu-Law yields the best results of peak-to-average power ratio (PAPR) reduction and bit error rate (BER). The simulation results showed a significant decrease in PAPR, with a reduction of 68.54% compared to the original signal without the reduction technique.

Background: The filter bank multicarrier (FBMC) with offset quadrature amplitude modulation (OQAM) is a promising future generation of wireless systems. However, like multicarrier modulations (MCM), FBMC/OQAM has a high peak-to-average power ratio (PAPR), which allows the FBMC/OQAM signal to pass through the nonlinear region of the high-power amplifier (HPA) in the time domain and causes in-band and out of band (OOB) distortion. Methods: In this paper, a new method to overcome this problem called multi-antennas PAPR (MAP) reduction is proposed. It consists of using I antennas in transmission and reception to transmit I FBMC/OQAM sub-signals with low PAPR. The complementary cumulative distribution function (CCDF), the bit error rate (BER), and the energy efficiency are used to evaluate the method's performance. Results: The simulation results showed that the new technique can reduce the PAPR of the original signal by more than half, achieve BER comparable to that of the original signal without HPA, and when the input back-off (IBO) equals 3dB, the error vector magnitude (EVM) result can be reduced from 19% to 7%. Conclusion: The PAPR, BER, and EVM of MAP technique are much better than the original system.
