Our laboratory focuses on signal processing technologies for RF-based sensing and communications. In 6G networks, integrated sensing and communication (ISAC), where communication networks also perform sensing functions, is emerging as a key technology. In autonomous driving and defense applications, radar systems are becoming increasingly important for real-time detection and recognition of targets under adverse weather and complex environments. Accordingly, our research encompasses 1) waveform design, AI- and quantum computing-based intelligent signal processing, and resource optimization for next-generation ISAC systems; and 2) radar signal processing, including imaging radar, synthetic aperture radar (SAR), sensor fusion, and simultaneous localization and mapping (SLAM).
