Contribution of non‐orthogonal multiple access signalling to practical multibeam satellite deployments

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.

A Hybrid PAPR Reduction Method Based on SLM and Multi-Data Block PTS for FBMC/OQAM Systems

Information, 2018
The filter bank multicarrier employing offset quadrature amplitude modulation (FBMC/OQAM) is a candidate transmission scheme for 5G wireless communication systems. However, it has a high peak-to-average power ratio (PAPR). Due to the nature of overlapped

PAPR Reduction in DCO-OFDM Based WDM VLC

Journal of Lightwave Technology, 2022
Visible light communication (VLC) can achieve high data rate transmission with multicarrier modulation techniques. The common variant is direct current (DC) optical orthogonal frequency division multiplexing (DCO-OFDM) which offers a spectral efficient modulation solution for VLC.

Structural Basis of the Light‐Switchable Interaction between an Azobenzene Side Chain in a Biosynthetic Protein and α‐Cyclodextrin

ChemistryOpen, Volume 15, Issue 1, January 2026.
X‐ray crystallographic analysis of super‐folder green fluorescent protein (sfGFP), a common reporter protein, displaying p‐(phenylazo)‐L‐phenylalanine (Pap) at amino acid position 39 on its surface in complex with α‐cyclodextrin (α‐CD) reveals an unexpected conformation of the photoswitchable side chain and illustrates its light‐dependent ...

Enhanced Sub-Block Partitioning and Effective Post-Processing for the PTS Algorithm

Tikrit Journal of Engineering Sciences
The transmitted OFDM is a multicarrier modulation technique for efficient and reliable data communication. This technique forces a major problem during the signal transmission process, which is a high peak-to-average power ratio (PAPR), leading to ...

Novel Iterative Clipping and Error Filtering Methods for Efficient PAPR Reduction in 5G and Beyond

IEEE Open Journal of the Communications Society, 2021
The physical-layer radio access of 5G New Radio (NR) and other modern wireless networks builds on the cyclic prefix (CP) orthogonal frequency-division multiplexing (OFDM), known to suffer from the high peak-to-average power ratio (PAPR) challenge.

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.

Generalized Discrete Fourier Transform for FBMC Peak to Average Power Ratio Reduction

IEEE Access, 2019
Filter bank multicarrier (FBMC) is a strong candidate as a waveform based technique in advanced wireless communication systems (e.g. 5G), as an alternative to orthogonal frequency division multiplexing (OFDM). Like all multicarrier modulation techniques,

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.
