Analysis of Hybrid PAPR Reduction Methods of OFDM Signal for HPA Models in Wireless Communications
IEEE Access, 2020 Orthogonal Frequency Division Multiplexing (OFDM) suffers from a high Peak-to-Average Power Ratio (PAPR). Designing a High Power Amplifier (HPA) with high PAPR is not a wise technique as it roots the amplifier to operate in a non-linear region which is ...

CE-OFDM-CDMA Phase Modulation for 5G System [PDF]
International Journal of Mathematical, Engineering and Management Sciences, 2021 In the present work, we propose a novel modulation scheme for 5G wireless communication system. Our contribution is to combine PM-OFDM (Phase Modulation Orthogonal Frequency Division Multiplexing) and CDMA (Code Division Multiple Access) to exploit their

Utilization of Compressed Sampling for PAPR Reduction in OFDM IEEE-802.11a System
Journal of Communications Software and Systems, 2021 Being spectrally efficient, easily implemented, and highly immune to selective channel imperfections and multipath fading, the Orthogonal Frequency Division Multiplexing (OFDM) can provide a sufficiently robust and high data rate modulation technique for

Precoding for PAPR Reduction in UW-OFDM [PDF]
IEEE Communications Letters, 2021 Unique Word Orthogonal Frequency Division multiplexing (UW-OFDM) is a variant of the multicarrier technique that has shown better bit error performance compared to cyclic prefixed (CP-)OFDM. Like other multicarrier techniques, UW-OFDM suffers from the high peak-to-average-power ratio (PAPR) problem, which is an obstacle ahead of practical ...
