IET Communications, Volume 19, Issue 1, January/December 2025.This article proposes a hybrid SLM+PTS+RNN algorithm to mitigate the high PAPR challenge in UFMC systems for B5G networks. The method significantly improves power efficiency (by 30%–40%) while maintaining BER and PSD performance, outperforming traditional PAPR reduction techniques.

Theoretical analysis of the trade-off between efficiency and linearity of the High Power Amplifier in OFDM context [PDF]
, 2012 International audiencePower efficiency and linearity are key parameters of amplification systems but they cannot be achieved simultaneously. A perfect linearity is observed when the power efficiency is low and vice versa.

Characterization of Nonlinearities in a Class-J Power Amplifier
Telfor Journal, 2018 We characterize the nonlinearities of our previously designed 10 W class-J power amplifier with a carrier at 1.5 GHz. We employ numerical simulations and real time adjacent channel power ratio (ACPR) measurements on the fabricated prototype.

Discrete Hartley matrix transform precoding-based OFDM system to reduce the high PAPR
ICT Express, 2019 The high peak-to-average power ratio (PAPR) is one of the major drawbacks of the orthogonal frequency division multiplexing (OFDM) systems that make non-linear distortion in practical implementation of high power amplifier (HPA).
