Jeonbuk National University (JBNU) Division of Electronics and Information Engineering doctoral student No Ye-hun has been selected for the “2026 Academic Next-Generation Support Program (Doctoral Student Research Incentive Grant Support Program)” funded by the Ministry of Education and the National Research Foundation of Korea.

This program supports creative and challenging research by domestic graduate doctoral students that is linked to their dissertations, fostering outstanding next-generation scholars. Selected researchers will receive a total of KRW 50 million in research funding over two years.

With this support, the doctoral student will conduct research on “a 100 MHz-bandwidth high-linearity, low-noise self-interference cancellation receiver for 6G full-duplex communications.” Full-duplex communication is a next-generation mobile communication technology that transmits and receives simultaneously within a single frequency band.

While it offers the advantage of more efficient use of limited frequency resources, it faces the technical challenge of effectively canceling self-interference—where the transmitted signal strongly leaks into the receiver—while maintaining the desired received signal quality.

The doctoral student intends to develop receiver integrated circuit (IC) technology for a 100 MHz wideband, high-linearity, low-noise self-interference cancellation receiver capable of stable signal reception even under strong self-interference conditions. The research will investigate circuit architectures and signal cancellation techniques that suppress wideband self-interference while minimizing degradation of the receiver’s noise and linearity performance, with the goal of securing core receiver technology for future 6G full-duplex wireless communication systems.

The research scope is expected to expand to the field of multi-channel high-speed memory interface circuits. Based on the high-speed and wideband signal transmission and interference suppression circuit design technologies to be accumulated during the research, the results are expected to be applicable to the development of technologies that reduce signal interference (crosstalk) in memory interfaces and improve signal integrity.

No Ye-hun expressed his gratitude to his advisor, Professor Im Dong-gu, and his lab colleagues “for guiding the research direction and providing generous support,” and said, “Through this research, I will advance self-interference cancellation receiver technology for 6G full-duplex communications and grow into a researcher who can contribute to enhancing the technological competitiveness of domestic industry in RF and analog integrated circuits and next-generation wired and wireless communications.”
