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

From the Modeling of Experiments to the Ab Initio Prediction of Rate Constants: Statistical Rate Theory for a Quantitative Understanding of Gas‐Phase Ion Chemistry

ChemPhysChem, Volume 27, Issue 8, 28 April 2026.
For directly comparing experimental results on gas‐phase ion reactions with the predictions from quantum chemical calculations, the latter must first be converted into rate constants. This review addresses the question of whether current methods of statistical rate theory can accomplish this task reliably. Statistical rate theory has long been used for

Fractional Fourier Domain PAPR Reduction

GLOBECOM 2025 - 2025 IEEE Global Communications Conference
High peak-to-average power ratio (PAPR) has long posed a challenge for multi-carrier systems, impacting amplifier efficiency and overall system performance. This paper introduces dynamic angle fractional Fourier division multiplexing (DA-FrFDM), an innovative multi-carrier system that effectively reduces PAPR for both QAM and Gaussian signals with ...

Modeling and Optimization of Frequency‐Doubled Radio‐Over‐Fiber Link Based on Deep Learning Technique

Advanced Photonics Research, Volume 7, Issue 3, March 2026.
This article proposes a deep learning (DL) approach for modeling and optimizing frequency‐doubled radio‐over‐fiber links. By collectively replacing traditional components with DL model, accurate system evaluation is achieved. Moreover, through an end‐to‐end architecture, performance optimization is accomplished.

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,

Expanded Phenotype of PAX2‐Related Papillorenal Syndrome: A Case Featuring FSGS, Atypical Retinopathy, Cerebellar Hypoplasia, and ADHD

Clinical Case Reports, Volume 14, Issue 2, February 2026.
ABSTRACT Papillorenal syndrome (PAPRS), or renal coloboma syndrome, is a rare autosomal dominant disorder caused by PAX2 mutations. It classically manifests with renal hypodysplasia and optic nerve anomalies. However, recent literature suggests an expanding phenotypic spectrum.
