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 ...

International Journal of Satellite Communications and Networking, Volume 44, Issue 1, Page 73-88, January/February 2026.The potential gains of NOMA were evaluated in a satellite system with heterogeneous receivers, after considering the use of specific DVB‐S2X MODCODs, along with the impact of non‐linearities. It was concluded that a judicious power allocation in NOMA, jointly optimized with the IBO of the PAs, can yield significant sum‐rate gains.

Peak-to-average power ratio reduction based on cross-correlation in OFDM systems [PDF]
, 2014 Two of the most important techniques of Peak-to-average power ratio (PAPR) reduction in orthogonal frequency division multiplexing (OFDM) systems are Partial Transmit Sequence PAPR (PTS-PAPR) and Cross-Correlation-PTS.

Research on Peak‐to‐Average Power Ratio Control Method for Switched Reluctance Pulse Generator
IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.Addressing the different requirements for peak output power when SRPG supplies power to pulse loads and DC loads, the peak‐to‐average power ratio (PAPR) is taken as the generation performance optimisation parameter. By investigating the power characteristics of the SRPG, the influence of control parameters on the PAPR is studied.

Spectrally Compatible Deceptive Jamming Waveform Design for Synthetic Aperture Radar Countermeasures
IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.This paper focuses on the design of synthetic aperture radar (SAR) deceptive jamming waveforms with spectrum‐compatible capability. By using the synthesised jamming waveform, successful deception against the hostile SAR system is demonstrated by generating false targets with high fidelity in both range and azimuth.

Journal of Computer Networks and Communications, Volume 2026, Issue 1, 2026.The sixth generation (6G) wireless networks are used to provide a large coverage, and also this generation needed to support different emerging applications in harsh areas with higher user equipment mobility. For the above case, a new modulation technique called orthogonal time–frequency space (OTFS) modulation has emerged as a promising technique to ...

International Journal of Numerical Modelling: Electronic Networks, Devices and Fields, Volume 38, Issue 5, September/October 2025.ABSTRACT In this article, we provide a novel, expanded, and adapted pruning approach for the Simplified Volterra Series (SVS) model that makes it applicable to a wider range of Power Amplifiers (PAs). The proposed Modified SVS (MSVS) model is then applied in a Digital Predistortion (DPD) architecture to linearize a 25 W Gallium Nitride (GaN) RF PA.
