The Institute for the Wireless Institute of Things at Northeastern University is looking for a Postdoctoral Research Associate to work on cutting-edge research on next-generation cellular networks, including O-RAN and 5G/6G wireless systems. The candidate will work with a team of students and PIs of the NSF-funded X-Mili project (https://lnkd.in/gdrKFgPP) to develop an open and programmable 5G testbed, based on standard-compliant components and radios operating in the sub-6 GHz and mmWave frequencies. The candidate will also contribute to research use cases on the testbed, to develop and test data-driven algorithms for the optimization and control of the base station protocol stack and configuration. We are looking for candidates with a strong understanding of systems and networks, in particular of 3GPP radio access network architectures and protocols, and with solid programming skills in C/C++/Python and familiarity with Linux systems and software-defined radios. Knowledge of FPGA (Xilinx RFSoC architectures) and/or CUDA programming and/or antennas and RF design are appreciated but not required. Interested candidates should email their CV and research statement to d.koutsonikolas@northeastern.edu.
