Professor Shin’s team received the Silver Award in the Communication & Networks category for their paper titled: "Embracing Beam-Squint Effect for Wideband LEO SATCOM: A Rainbow Beamforming Approach." The research tackled the uplink transmission bottleneck in Low Earth Orbit (LEO) satellite communication systems, a core technology for 6G networks. The team proposed an innovative paradigm shift by utilizing the beam-squint effect, traditionally seen as a cause of performance degradation, to enhance communication efficiency.

Their groundbreaking approach led to the development of a new signal amplification technology that, through rigorous experimentation, demonstrated 10 times more simultaneous users supported compared to existing technologies and 3 times faster communication speeds, garnering high praise from the evaluation committee.

Juha Park, a Master’s student from the School of Electrical Engineering, expressed gratitude, saying, “Despite the mathematical challenges and trial-and-error during the research process, the continuous support and guidance from Professor Shin made this consecutive win possible. I am committed to further dedicating myself to research.”

This consecutive recognition at the Samsung Human-Tech Paper Award not only highlights the innovative achievements of Professor Shin's research team but also underscores the ongoing excellence and leadership of Korea University School of Electrical Engineering in the field of advanced communication technologies.
