In this paper, we evaluate the effect of applying peak-to-average power ratio (PAPR)
reduction and digital pre-distortion (DPD) on two types of radio frequency power amplifiers …

In this paper, we present a method to limit the generation of signal peak power at the output
of a digital pre-distorter that is applied to a RF power amplifier (PA) operating in strong …

Power 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 …

In order to enhance spectrum utilization and decrease transmission delay, the 6th
generation mobile networks (6G) system adopts full-duplex (FD) mode. Simultaneous …

This paper investigates the issue of “predistorter blow-up,” ie, uncontrolled peak expansion
caused by the predistorter. To control the peak expansion, an extension of the multistep …

Models are commonly used to simulate events and processes, and can be constructed from
measured data using system identification. The common way is to model the system from …

Digital predistortion (DPD), based on complex-valued memory polynomials (MP), is
established as an efficient method for power amplifier (PA) linearization. The DPD facilitates …

Les modulations multiporteuses apparaissent aujourd'hui comme une technologie éprouvée
pour la transmission de données à haut-débits sur des canaux pouvant être très perturbés …

In this study, the authors look into digital predistortion and its combination with the peak‐to‐
average power ratio (PAPR) reduction technique in the case of orthogonal frequency …

Les amplificateurs de puissance sont au centre des systèmes actuels de
télécommunications. Leur linéarité (pour préserver la qualité des données transmises) et …
