Welcome to WCS Lab
About us
Wireless Communication & Sensing Lab (WCSL) was established in September 2021 when Prof. Jeongsik Choi joined Kyungpook National University. We are interested in fundamental and application issues on artificial intelligence (AI) for wireless and sensing technologies in general.
Currently, we are working on the following topics:
- Implementing SDR(software defined radio)-based transceivers using RFSoC device
- ISAC(integrated sensing and communication) system and channel study for 6G
- Precise indoor navigation techniques using wireless and various sensors
- Big data processing pipeline to exploit mobile user data
- Radar signal processing / perception for autonomous driving vehicles
- Machine learning-based transmission techniques for 5G/6G networks
- Wireless sensing and sensor-fusion applications (e.g., Wi-Fi sensing)
Notice
We are recruiting highly self-motivated undergraduate interns and MS/PhD students who have interests in AI for wireless and sensing applications. (Please send an e-mail to jeongsik.choi [at] knu.ac.kr)
