Hanjun Park

I am interested in finding optimized solutions or developing an underlying theory given complex, constrained, or high-dimensional experimental conditions. I made contributions using statistical approach/analysis.

In short, my research interest is:

① Next Generation Communications
    - Machine Learning in Wireless Communications, Fingerprint Localization, Channel Charting, CSI Compression
    - Reconfigurable Intelligent Surface (RIS)
    - Information Theory
