Performance Analysis of the Two-Piecewise Linear Companding Technique on Filtered-OFDM Systems
Filtered orthogonal frequency division multiplexing (F-OFDM) is one of the most prominent waveform candidates when it comes to fifth-generation (5G) wireless communication and beyond.

Performance evaluation of PAPR reduction in FBMC system using nonlinear companding transform
Filter Bank Multicarrier with Offset Quadrature Amplitude Modulation (FBMC/OQAM) is one of the best waveforms used in 5G communications. The FBMC is a multicarrier modulation system (MCM) which suffers from high peak to average power ratio (PAPR) causing

Low-Complexity Selective Mapping Methods for Multicarrier Faster-Than-Nyquist Signaling
Multicarrier faster-than-Nyquist (MFTN) signaling is a high spectral efficiency transmission scheme, which is promising in the future communication. One of the major problems of MFTN signaling is high peak-to-average power ratio (PAPR).

Peak shrinking and interpolating for PAPR reduction in M-IFoF-based mobile fronthaul
We apply a Peak Shrinking and Interpolating (PSI) scheme to improve the Peak-to-Average Power Ratio (PAPR) performance in Multiple Intermediate-Frequency-over-Fiber (M-IFoF) based mobile fronthaul.

A new PAPR reduction in OFDM systems using PTS combined with APPR for TWTA nonlinear HPA [PDF]
In this paper, we propose a new Peak-to-Average Power Ratio (PAPR) reduction technique using a partial transmit sequence (PTS) combined with adaptive peak power reduction (APPR) methods.

Performance and Implementation Evaluation of TR PAPR Reduction Methods for DVB-T2
High Peak to Average Power Ratio (PAPR) is a critical issue in multicarrier communication systems using Orthogonal Frequency Division Multiplexing (OFDM), as in the Second Generation Terrestrial Digital Video Broadcasting (DVB-T2) system.
