Performance evaluation of PAPR reduction in FBMC system using nonlinear companding transform

ICT Express, 2019
Filter Bank Multicarrier with Offset Quadrature Amplitude Modulation (FBMC/OQAM) is one of the best waveforms used in 5G communications. The FBMC is a multicarrier modulation system (MCM) which suffers from high peak to average power ratio (PAPR) causing

A Unified Multicarrier Modulation Framework

CoRR, 2016
Orthogonal frequency division multiplexing (OFDM) has been recently recognized as inadequate to meet the increased requirements of the next generation of communication systems. A number of alternative modulation solutions, based on the use of filter banks, have thus been proposed and are currently being considered as candidate waveforms for the ...

CDMA Transmission with Complex OFDM/OQAM

EURASIP Journal on Wireless Communications and Networking, 2007
We propose an alternative to the well-known multicarrier code-division multiple access (MC-CDMA) technique for downlink transmission by replacing the conventional cyclic-prefix orthogonal frequency division multiplexing (OFDM) modulation by an advanced ...

Frame design for 5G multicarrier modulations [PDF]

2015 International Wireless Communications and Mobile Computing Conference (IWCMC), 2015
Orthogonal Frequency Division Multiplexing (OFDM) transmission technique has been considered for the 4G LTE-Advanced system because of its high performance and low complexity. In the new 5G scenario this type of modulation is not properly suited because of the additional requirements for very high spectral efficiency, low latency and low out-of-band ...

Comparative Analysis of Optical Multicarrier Modulations: An Insight into Machine Learning-based Multicarrier Modulation

Gazi University Journal of Science, 2021
The performances of various optical multicarrier modulation schemes have been investigated in this work by comparatively analyzing the bit error rate response relative to the signal to noise ratio metric. The machine learning-based multicarrier modulation (MLMM) approach was proposed and adopted as a method to improve the bit error rate response of the

Wireless Multicarrier Communications via Multipulse Gabor Riesz Bases

EURASIP Journal on Advances in Signal Processing, 2006
We introduce multipulse multicarrier (MPMC) modulation, a wireless communication scheme that augments traditional single-pulse multicarrier systems by using multiple pulses at the transmitter and the receiver. The mathematical foundation of MPMC systems

Decoding Schemes for FBMC with Single-Delay STTC

EURASIP Journal on Advances in Signal Processing, 2010
Orthogonally multiplexed Quadrature Amplitude Modulation (OQAM) with Filter-Bank-based MultiCarrier modulation (FBMC) is a multicarrier modulation scheme that can be considered an alternative to the conventional orthogonal frequency division multiplexing

Peak-to-Average Power Ratio of Multicarrier Faster-Than-Nyquist Signals: Distribution, Optimization and Reduction

IEEE Access, 2018
Multicarrier faster-than-Nyquist (MFTN) is a spectral efficient transmission scheme for future communication systems. However, as one of the most important drawbacks of multicarrier transmission systems, the peak-to-average power ratio (PAPR) of MFTN ...

Basics and Perspectives of Visible and Near‐UV Light‐Induced Defluorination of Perfluoroalkylsubstances by Semiconductor Nanocrystals

ChemPhotoChem, Volume 10, Issue 6, June 2026.
This review highlights recent advances in the light‐driven destruction of persistent per‐ and polyfluoroalkyl substances (PFASs) using semiconductor nanocrystals. By exploiting nonlinear photophysical and photochemical processes, these nanomaterials harness energy‐efficient visible and near‐UV light‐emitting diodes (LEDs) to drive extreme reduction ...
