Smail Bachir

Smail Bachir is an Associate Professor specializing in Automatic Control and Systems at the University of Poitiers, France, with affiliations at both ENSIP (École Nationale Supérieure d'Ingénieurs de Poitiers) and ISAE-ENSMA (Institut Supérieur de l'Aéronautique et de l'Espace - École Nationale Supérieure de Mécanique et d'Aérotechnique). His research focuses on electrical machines diagnosis, RF power amplifiers, and signal processing for wireless communications systems, with over 80 publications spanning from 2001 to 2024.

Dr. Bachir's research interests span Automatic Control, Electrical Machines Diagnosis, RF Power Amplifiers, Signal Processing, Digital Predistortion, PAPR Reduction, and Fault Diagnosis in Induction Machines. His work bridges theoretical control systems with practical applications in wireless communications and power electronics. He has made significant contributions to the modeling and linearization of RF power amplifiers, developing novel techniques for digital predistortion that improve signal quality in modern wireless systems. His research on induction machine fault detection demonstrates his ability to address both industrial and theoretical challenges.

Analysis of his recent publications reveals a strategic evolution from electrical machine diagnostics to cutting-edge RF communications technology. His most impactful work focuses on digital predistortion techniques using Feedback-Wiener models, which have advanced linearization methods for RF power amplifiers in aeronautical applications. He has also pioneered innovative PAPR (Peak-to-Average Power Ratio) reduction approaches that combine tone reservation with clipping and interleaving techniques for multicarrier systems. His 2023-2024 work on Doherty power amplifiers with 40% fractional bandwidth represents significant progress in wideband amplifier design for next-generation wireless systems.

Dr. Bachir maintains strong collaborative relationships with researchers across France, frequently working with Claude Duvanaud, Tayeb Bouazza, and Jean-Claude Trigeassou. His publications appear in high-impact journals including IEEE Transactions on Industrial Electronics, IEEE Microwave and Wireless Technology Letters, and EURASIP Journal on Wireless Communications and Networking, demonstrating both academic rigor and practical relevance to industry challenges.
