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). Hosted primarily at imec in Leuven, Belgium, the project is supervised by Prof. Sofie Pollin (KU Leuven) and co-supervised by Prof. Claude Dessert (IMEC). The research is embedded in the WaveCoRE research centre within KU Leuven’s Department of Electrical Engineering, which specializes in wireless communication fundamentals and systems. The project addresses the challenges posed by the FR3 band, which offers a promising balance between capacity and coverage for future cellular networks but introduces complexities due to its wide frequency range, non-uniform channel propagation, and hardware constraints. The research will investigate multiple-antenna communication schemes, flexible transceiver architectures, and dynamic spectrum allocation strategies. It will also explore the use of advanced analog components, power amplifiers, and semiconductor technologies, leveraging imec’s expertise in nanoelectronics. The project aims to develop novel communication algorithms and architectures that optimize power-performance trade-offs and support real-time reconfigurability for diverse deployment scenarios. AI and machine learning tools may be used to guide the selection and optimization of architectures for specific sites. As a PhD student, you will engage in literature review, modelling and simulation, and experimental design, working in a multidisciplinary environment alongside experts in wireless communication, signal processing, digital and analog design, and machine learning. You will have access to world-class facilities, participate in international conferences, and collaborate with leading researchers. The position offers a competitive salary, funding for up to four years (subject to positive evaluations), and the opportunity to earn a PhD from a highly ranked university. Applicants should have a master’s degree in electrical engineering, telecommunication engineering, or a related field, with exceptional grades and proficiency in English. Experience in wireless communications, signal processing, channel modelling, and hardware implementation is desirable, as is proficiency with Matlab or Python. Strong interpersonal skills and the ability to work in an international team are required. KU Leuven is committed to diversity, inclusion, and equal opportunity. Applications must be submitted via the imec website, referencing code 2026-213. For further information, contact Prof. Sofie Pollin or Prof. Claude Dessert.
