Wireless communication technology has evolved over five generations, but the demand for higher efficiency, availability, and reliability is never-ending. The physical layer of 5G and 6G networks revolves around the multi-antenna MIMO technology. 5G uses 64 antennas in each base station and 4 antennas in devices, which might grow by 5-10 times in 6G. These antennas can be used for beamforming, spatial multiplexing, and integrated communication and sensing (ISAC).
In this postdoc project, you will contribute to cutting-edge research on 6G MIMO technology and develop new communication theory, concepts, and algorithms. The focus might be on Gigantic MIMO, cell-free networks, near-field communications, or ISAC for mid-band or higher frequencies. We believe a successful postdoc period builds on your current skills but expands them by targeting new research challenges and using new methods.
The research will be focused on the physical and media access control layers. Methods from MIMO communication theory, array signal processing, optimization, and machine learning will likely play a vital role. The research will mainly be theoretical, but KTH has testbeds for potential experiments. However, we are not looking for microwave doctors because no antennas or hardware will be built.
In this project, you will join the world-leading research group of Prof. Emil Björnson (IEEE Fellow, Clarivate Highly Cited Researcher) and work at the Division of Communication Systems at the EECS school. The research is funded by external projects, so there will be good opportunities to interact with the telecom industry.
You can read the paper “Enabling 6G Performance in the Upper Mid-Band by Transitioning From Massive to Gigantic MIMO”, 10.1109/OJCOMS.2025.3576931, to learn more about the research we plan to conduct within this project.
You need to satisfy the minimum requirements below and will be evaluated based on the listed preferred qualifications.
