Undergraduate Researcher

Intelligent Radio Sensing Lab (IRS Lab), DGIST · Advisor: Prof. Jae‑Ho Choi

• Passive Wi-Fi sensing. Implemented a passive sensing pipeline on a USRP-2921, using reference and surveillance channels with CAF-based Range–Doppler processing.
• IoTJ experimental support. Assisted with USRP setup and preliminary signal checks for passive Wi-Fi vital-sign sensing experiments supporting the accepted IoTJ paper [J1].
• Drone sensing experiments. Conducted measurements with a USRP X410 and a DJI Matrice 4E; data analysis is in progress. Research project.

Undergraduate Researcher

Communication & Signal Processing Lab (CSP Lab), DGIST · Advisor: Prof. Ji‑Woong Choi

• C-V2X sidelink measurement. Set up the Linux environment for the OBU and RSU hardware and carried out field experiments on real-time video transmission over 5G C-V2X sidelink in a V2I scenario, measuring RSSI, estimated SNR, block error rate (BLER) and throughput for the JCCI 2025 paper.
