Communication Lab
Digital Communication Laboratory (DCLAB), led by Prof. Yong. H. Lee was established in 1989 as a part of Department of Electrical Engineering and Computer Science (EECS) at Korea Advanced Institute of Science and Technology (KAIST).
Major research areas can be classified into two parts:
- Physical layer design
-
- Cognitive radio system design and analysis
-
- Interference management
-
- Cooperative communications
- Communication signal processing
-
- Signal processing for relay systems
- Digital signal processing techniques
