Currently, we are interested in fundamentals of the next-generation wireless communication systems as follows.
- Dynamic Spectrum Access (DSA)
-
While demand for the limited spectrum resource is causing the spectrum scarcity, DSA has recently received a great attention due to the ability to improve spectrum utilization. RCLab is working on political and engineering issues related to DSA such as Cognitive Radio (CR) and modern spectrum management.
- Wireless Channel Modeling
- To guarantee reliable performance measurement of the next generation wireless communication systems, practical observation and modeling about wireless channel need to be established. We have developed a novel modeling about wireless channels of MIMO systems, cooperative systems and hand-over situation.
- Interference Management
- Recently, as a variety of wireless systems or services are being coexisted, researches about resolving and analyzing interference among the different systems or system-internally are more important. Technical analysis and solutions for interference management are currently being studied.
