Kim Yoo-sung, a professor of software department, won the 2023 Spectrum Challenge Competition

○ The CSI Lab team has won first place for four consecutive years since 2020

○ Development of efficient frequency co-use plan in next-generation Wi-Fi environment

Software department CSI Lab. Park Tae-gun (Master's Course), Nine-ho (Undergraduate Research Institute), Heo Chan-yong (Intern), and Kim Yoo-sung's team won first place in the final round of the 2023 Spectrum Challenge hosted by the Korea Electronics and Telecommunications Research Institute (ETRI).

The Spectrum Challenge has been held annually since 2019 in accordance with the National R&D Plan with the aim of developing a government-led research and development system into an open challenge competitive research and development system.

This year's Spectrum Challenge was held for five weeks as a final competition between excellent teams that advanced to the winner's match from 40 teams participating in the competition.

There are two types of challenges, Type 1 identifies the propagation characteristics used in a given propagation environment through AI technology, and Type 2 develops reinforcement learning algorithms for resource allocation and scheduling resistant to dynamic environmental changes. In this competition, Hanyang University, Handong University, and Korea University, including our university, were selected as excellent teams.

Sungkyunkwan University's Computer Systems and Intelligence Lab (CSI Lab) team won the first place in the algorithm development type 2 to find a radio resource allocation technique that can optimize radio utilization efficiency and communicate in an unlicensed communication environment. In particular, the CSI Lab team has achieved the feat of winning first place for four consecutive years.
