This PhD position at KU Leuven, in collaboration with imec, focuses on developing innovative transceiver architectures for cellular communications in the FR3 band (7–24 GHz). The research is hosted primarily at imec in Leuven, Belgium, and supervised by Prof. Sofie Pollin (KU Leuven) and Prof. Claude Dessert (IMEC). Imec is a world-leading research and innovation hub in nanoelectronics and digital technologies, working closely with KU Leuven to combine fundamental research with industrial partnerships. The WaveCoRE research centre in KU Leuven’s Department of Electrical Engineering (ESAT) specializes in wireless communication fundamentals and systems, with the Networked Systems group led by Prof. Pollin covering areas such as Cell-Free Massive MIMO, Non-Terrestrial Networks, IoT, joint communication and sensing, machine learning-based signal processing, and SWIPT. The project addresses the exponential growth of communication networks and the need for new frequency bands to meet increasing user demands. While mm-wave frequencies (FR2) offer bandwidth, challenges in technology readiness and propagation have led the industry to explore the FR3 band, which provides a balance between capacity and coverage but introduces unique research challenges. These include non-uniform channel behavior across the band, varying antenna integration strategies, differences in analog component performance, and the need for flexible systems that adapt to dynamic spectrum allocation and propagation conditions. The research will investigate multiple-antenna communication schemes, flexible architectures, and the use of AI tools to optimize base station deployment and operation. As a PhD student, you will gain a fundamental understanding of channel propagation and hardware constraints in the FR3 band, propose novel transceiver architectures and algorithms, and explore solutions for real-time reconfigurability and scenario-specific optimization. You will work within a multidisciplinary team at imec, collaborating with experts in wireless communication, signal processing, digital and analog design, mm-wave technology, and machine learning. The position offers a unique opportunity to contribute to the future of wireless networks, publish in top journals and conferences, and build an international network. Applicants should have a master’s degree in electrical engineering, telecommunication engineering, or a related field, with strong grades and English proficiency. Expertise in wireless communications and signal processing is required, and knowledge of channel modelling and hardware implementation is advantageous. Proficiency in Matlab or Python and strong interpersonal skills are expected. The scholarship covers up to four years, with competitive salary, access to world-class facilities, and funding for conference participation. KU Leuven and imec provide an inclusive, diverse, and supportive research environment. Applications must be submitted via the imec website, referencing code 2026-213.
