Artificial Intelligence for Wireless

AI has great potentials to improve the performance of conventional communication systems. It can enhance the performance of each block of communication systems or jointly optimize the whole transmission and reception procedure, such as so called end-to-end (E2E) communication systems. In addition, AI can break the limit of conventional communication systems by efficiently exploiting additional information, such as sensor readings from mobile devices. Our effort in this topic include designing intelligent transmission/resource allocation techniques, distributed learning over wireless, and so on.

Automotive Radar Signal Processing and Perception


Mobile Navigation and User Data Processing Pipeline

  • Machine learning-based transmission techniques for 5G/6G networks
  • Precise indoor navigation solutions using wireless and IMU/vision sensors
  • Designing big data processing pipeline to handle unlabeled mobile user data
  • Wireless sensing and sensor-fusion techniques (e.g., Wi-Fi sensing)
  • Radar signal processing / perception for autonomous driving vehicles

Past Research Area

The past research areas include radio propagation channel measurement/modeling for sub 6GHz and mmWave frequency bands, indoor/outdoor ray-tracing simulation, and design of various transmission techniques for wireless communication systems.
