Both scheduling and multi-input-multi-output (MIMO) antenna techniques 
have attracted a lot of interest in the wireless community recently. 
On one hand, wireless scheduling techniques can exploit a new type of 
diversity -- multiuser diversity -- to improve the spectral efficiency 
of wireless data networks. On the other hand, multiple transmit and 
receive antennas are an important means to increase either the diversity 
of combating channel fading or the degrees of freedom for communications 
(i.e., capacity). Such a fundamental tradeoff between diversity and 
spatial multiplexing in the MIMO system leads to an interesting fact 
that the capacity improvement of a MIMO system may come at the cost of 
smaller cell coverage. This talk aims to provide a unified point of view 
of how all types of gains -- multi-user diversity, multi-antenna diversity, 
and the spatial multiplexing - can be simultaneously achieved. 


Biography
%%%%%%%%%

Dr. Li-Chun Wang received the B.S. degree from National Chiao Tung 
University , Taiwan, R. O. C. in 1986, the M.S. degree from National 
Taiwan University in 1988, and the Ms. Sci. and Ph. D. degrees from 
the Georgia Institute of Technology , Atlanta, in 1995, and 1996, 
respectively, all in electrical engineering.  From 1990 to 1992, he 
was with the Telecommunications Laboratories of the Ministry of 
Transportations and Communications in Taiwan (currently the Telecom 
Labs of Chunghwa Telecom Co.). In 1995, he was affiliated with Bell 
Northern Research of Northern Telecom, Inc., Richardson, TX. From 1996 
to 2000, he was with AT&T Laboratories, where he was a Senior Technical 
Staff Member in the Wireless Communications Research Department. Since 
August 2000, he has been an Associate Professor in the Department of 
Communication Engineering of National Chiao Tung University in Taiwan. 
His current research interests are in the areas of cellular architectures, 
radio resource management, and propagation channel modeling. Specific 
topics include hierarchical cellular architectures, macrodiversity 
cellular systems, dynamic channel allocations, power control, 
microcellular interference modeling and wireless internet system 
engineering issues. Dr. Wang was a co-recipient (with Gordon L. Stuber 
and Chin-Tau Lea) of the 1997 IEEE Jack Neubauer Best Paper Award from 
the IEEE Vehicular Technology Society. He is an associate editor for the 
IEEE Transactions on Wireless Communications and holding three US patents.
