Peak-to-Average Power Ratio Reduction of FBMC/OQAM Signal Using a Joint Optimization Scheme

IEEE Access, 2017
Owing to the signal structure difference between the filter bank multicarrier with offset quadrature amplitude modulation (FBMC/OQAM) and the orthogonal frequency-division multiplexing (OFDM) systems, the existing technologies to reduce the peak-to ...

Exact Analysis of SIR Performance for the Mobile OFDM Communication Systems Over the Underwater Acoustic Channel

Electronics Letters, Volume 62, Issue 1, January/December 2026.
1.This paper develops an analytical model to calculate the signal‐to‐interference ratio performance of mobile orthogonal frequency division multiplexing underwater acoustic (UWA) communication systems. 2.The model accounts for UWA channel distortion and non‐uniform Doppler effects, maintaining high accuracy across a range of Doppler shift magnitudes. 3.

Integrative Transcriptomic and Phosphoproteomic Analysis Reveals Key Components of the SnRK1 Signaling Network in Rice

Plant Direct, Volume 9, Issue 11, November 2025.
ABSTRACT SnRK1 is an evolutionarily conserved protein kinase belonging to the SNF1/AMPK family of protein kinases that is central to adjusting growth in response to the energy status. Numerous studies have shown adaptive and developmental roles of SnRK1, but the understanding of the SnRK1 signaling network in monocots is limited.

A Novel FBMC/QAM Scheme to Eliminate the Error Floor in Multipath Channels

IET Communications, Volume 19, Issue 1, January/December 2025.
This paper proposes a cyclic prefix–based filter bank multicarrier with quadrature amplitude modulation (CP‐FBMC/QAM) scheme to eliminate the error floor and simplify the receiver in multipath fading channels. Moreover, to avoid the increase of out‐of‐band (OOB) radiation caused by the CP insertion, we propose a prototype filter optimization problem ...

A Discrete Bit Loading Algorithm for FBMC/OQAM [PDF]

IEEE Signal Processing Letters, 2012
In this letter the discrete rate maximization problem is investigated for FBMC/OQAM. The analysis reveals that if there is crosstalk certain bit allocations violate the power constraints. Aiming at ensuring the feasibility along with alleviating the complexity we have devised a novel iterative algorithm, which always converges. Simulation-based results
