Research


I was as a senior member of technical staff with Shinsegi Telecomm Inc., Seoul, Korea from July 1994 to Feb. 2000, which is one of the first CDMA cellular operators in the world. Since CDMA had started to be commercially applied near 1995, my contributions were mainly made in installing and implementing the new wireless system. I also took part in the standardization activity of localizing IS-95 and related standards (i.e. IS-97, IS-98, etc.) so that they could be applied on Korean IS-41 based mobile networks.

From 2003 to 2005, I was involved in constructing WiBro standard as a member of Steering Committee as well as Evaluation Committee. In addition, I proposed an idea of quality-based channel state reporting, which was finally accepted as a contribution in IEEE802.16d/e.   

Research Interests

Due to rapid increase in the number of wireless mobile subscribers and their demands for high-speed multimedia communications, efficient spectrum or radio resource management is of great importance. The primary intent of my research is to provide the efficiency in design and implementation of wireless communication systems or networks. My research interests are in the area of, but not limited to:

Link-level Simulators(constructed in C/C++)

    We have developed some link level simulation tools including the following systems:

 

System-level Simulators(constructed in C/C++)

    We have developed several system level simulation tools including the following systems:
