Lund University Lund, Sweden

Researcher at ICARUS

Conducting research on machine learning (ML) and artificial intelligence (AI) algorithms for the expedition project entitled intelligent cell-free access for wireless ubiquitous services (ICARUS) funded by Wallenberg AI, autonomous systems and software program (WASP).

• Proposed joint analog beam selection and digital beamforming solutions in millimeter-wave cell-free massive MIMO systems. Exploited ML algorithms including support vector machine, multi-layer perceptron, and random forest.

• Proposed sparse channel estimation in millimeter-wave channels by expectation maximization based sparse Bayesian learning via vector approximate message passing aka belief propagation in graphical models, i.e., probabilistic ML approaches.

• Proposed joint user / access point selection and beamforming in cell-free networks by sparse group LASSO solution.

• Proposed a new iterative thresholding algorithm, NCISTA plus FCSA, for MR image reconstruction.
