“…As opposed to the traditional partial transmission sequence methodology by Lu et al [ 21 ] optimization method is based on dynamic programming (DP). A reduced signal PAPR is achieved by using the DP in this operation to determine the ideal phase twiddle factor.…”

“…In order to further enhance the performance of FBMC/OQAM, hybridization of clipping with other techniques is suggested. [9] proposes an alternative based on clipping combined with non-linear companding techniques employing discrete fourier transform (DFT) spread with the polyphase network. The simulations produced good results in lowering the PAPR while maintaining acceptable BER performance.…”

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.

“…When compared to other qualities, several researchers propose improvements to the OFDM waveform to reduce spectrum contamination and sensitivity to carrier frequency offset. Recently GFDM, FBMC [7], UFMC [8], and BFDM [9] have been proposed to replace OFDM. Advancements and replacements to the OFDM waveform have been presented in recent research.…”

High data rates, extremely low power consumption, and minimal end-to-end latency are considered to be mandatory requirements for 5G wireless networks. Rapid improvements in design and performance of 5G physical layer waveforms have become necessary. The drawback of Orthogonal Frequency Division Multiplexing (OFDM) is high PAPR, that causes signal distortion, which reduces system efficiency. Generalized frequency division multiplexing (GFDM) is a promising non-orthogonal multicarrier transmission scheme, which has recently received a great deal of attention towards future fifth generation (5G) wireless networks. It overcomes the limitations of orthogonal frequency division multiplexing (OFDM), while preserving most of the advantages of it. Selective Level mapping (SLM) is one of the PAPR reduction techniques, that uses the phase shift technology. In this paper, SLM based on Chaotic Biogeography Based Optimization (CBBO) algorithm is proposed to offer an efficient solution to the problem of high PAPR, existing in the GFDM waveforms. Experimental results prove that, the proposed CBBO-SLM technique provides significant improvement in terms of PAPR reduction, as compared to the conventional SLM methods, such as conventional GFDM and OFDM-SLM. The proposed novel scheme is most suitable for QAM and QPSK applications, as it provides good PAPR reduction performance, at lower computational complexity.
