Hyung-Joo Moon

I am a postdoctoral researcher at Yonsei University, South Korea, working with Prof. Chan-Byoung Chae. My research has covered diverse wireless communication systems, including UAV/satellite communications and massive MIMO. I am currently exploring site-specific AI models, digital twins, and cross-layer intelligence toward AI-RAN architectures.
