International Journal of Numerical Modelling: Electronic Networks, Devices and Fields, Volume 38, Issue 5, September/October 2025.ABSTRACT In this article, we provide a novel, expanded, and adapted pruning approach for the Simplified Volterra Series (SVS) model that makes it applicable to a wider range of Power Amplifiers (PAs). The proposed Modified SVS (MSVS) model is then applied in a Digital Predistortion (DPD) architecture to linearize a 25 W Gallium Nitride (GaN) RF PA.

Analysis of Power Amplifier Modeling Schemes for Crosscorrelation Predistorters [PDF]
, 2004 Amplification of signals with fluctuating envelopes leads to distortion because of non-linear behavior of the Power Amplifier (PA). Digital Predistortion can counteract these non-linear effects.

On-board signal predistortion for digital transparent satellites [PDF]
2015 IEEE 16th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2015 On-board processing (OBP), a paradigm that allows for manipulation of the signal at the satellite transponder, is being embraced by a large section of the satellite community. Exploiting OBP can lead to efficient implementation, bandwidth saving, lower redundancy, and better performance.

Performance Analysis of MIMO Links With Non‐Isolated Active Antenna Arrays
Microwave and Optical Technology Letters, Volume 67, Issue 8, August 2025.ABSTRACT In this paper, we analyze the performance of non‐isolated active arrays in a multiple‐input multiple‐output (MIMO) system. When ferromagnetic‐type isolators are removed in the transmitter (Tx) chains, the antenna mutual coupling will dynamically change the load impedance seen by the power amplifiers (PAs) at their outputs, which subsequently ...

Binary Search‐Based Division (BSBD): A Technique for Efficient Division in Hardware
Journal of Electrical and Computer Engineering, Volume 2025, Issue 1, 2025.The division techniques play a key role in several computer‐implemented algorithms and applications; regrettably, they impose significant implementation constraints that hinder parallelization. The proposed binary search‐based division (BSBD) technique is inherited from the variable latency dividers, which have the potential to adjust the quotient bit ...

Intra‐scan RF power amplifier drift correction
Magnetic Resonance in Medicine, Volume 92, Issue 2, Page 645-659, August 2024.Abstract Purpose The drift in radiofrequency (RF) power amplifiers (RFPAs) is assessed and several contributing factors are investigated. Two approaches for prospective correction of drift are proposed and their effectiveness is evaluated. Methods RFPA drift assessment encompasses both intra‐pulse and inter‐pulse drift analyses.
