H. Shaiek

H. Shaiek is a Professor at Conservatoire national des arts et métiers (CNAM Paris), affiliated with the CÉDRI Laboratory within the École d'ingénieurs. His research focuses on wireless communications, particularly 5G/6G systems, signal processing techniques, and power amplifier linearization. He completed his Habilitation à diriger des recherches (HDR) in 2022 with the thesis 'Multi-carrier waveforms for 5G and beyond systems: from power amplifier impairments to energy efficiency enhancement,' demonstrating his senior academic status in the French system.

Shaiek's research interests center around wireless communications technologies, with particular expertise in power amplifier linearization, PAPR (Peak-to-Average Power Ratio) reduction techniques, FBMC-OQAM systems, and RIS (Reconfigurable Intelligent Surface) assisted communications. His work bridges theoretical signal processing with practical implementation challenges in next-generation wireless systems. Recent research has increasingly incorporated machine learning approaches for channel equalization and power amplifier post-distortion.

Analysis of his publication trends from 2021-2025 reveals a clear evolution toward 6G technologies, with growing emphasis on RIS-assisted communications, cell-free MIMO architectures, and hybrid OTFS-OFDM frameworks. His work consistently addresses the practical implementation challenges of theoretical wireless concepts, particularly concerning power efficiency and hardware constraints in broadcasting and mobile systems.

As an HDR holder, Shaiek supervises doctoral research and contributes to major research projects like ANR POSEIDON. His laboratory work within CÉDRI focuses on electronics and signal processing, collaborating with institutions like CEA LETI. He has developed experimental testbeds for post-OFDM waveforms and contributed to standardization efforts in next-generation broadcasting systems (DVB-T2, ATSC 3.0).
