Abstract:

Different technologies for 5G wireless networks have been continuously developed to achieve higher system performance. Advanced network topologies have been investigated to provide higher communication bandwidth, which bringing the network closer to mobile users. Along with the power model of future base stations developed by existing literatures, novel structure of distributed antenna system (DAS) focuses on centralized processing for spatially distributed antennas. This talk will provide insights on this type of provisioning paradigm from the perspective of energy efficiency (EE). Contributed by the design of radio resource management, this system promises to offer a larger throughput at reduced total power consumption. The results show that the merit of additional spatial degree of freedom from DAS comes with an increased EE gain by adopting spatial water-filling power allocation.

Kai-Ten Feng received the B.S. degree from the National Taiwan University, Taipei, Taiwan, in 1992, the M.S. degree from the University of Michigan, Ann Arbor, in 1996, and the Ph.D. degree from the University of California, Berkeley, in 2000.

Since August 2011, he has been a full Professor with the Department of Electrical and Computer Engineering, National Chiao Tung University (NCTU), Hsinchu, Taiwan, where he was an Associate Professor and Assistant Professor from August 2007 to July 2011 and from February 2003 to July 2007, respectively. He has also been serving as the Director of Institute of Communications Engineering at NCTU since February 2015. From July 2009 to March 2010, he was a Visiting Research Fellow with the Department of Electrical and Computer Engineering, University of California at Davis. Between 2000 and 2003, he was an In-Vehicle Development Manager/Senior Technologist with OnStar Corporation, a subsidiary of General Motors Corporation, where he worked on the design of future Telematics platforms and in-vehicle networks. His current research interests include broadband wireless networks, cooperative and cognitive networks, smart phone and embedded system designs, wireless location technologies, and intelligent transportation systems.

Dr. Feng received the Best Paper Award from the Spring 2006 IEEE Vehicular Technology Conference, which ranked his paper first among the 615 accepted papers. He also received the Outstanding Youth Electrical Engineer Award in 2007 from the Chinese Institute of Electrical Engineering, and the Distinguished Researcher Award from NCTU in 2008, 2010, and 2011. He has also served on the technical program committees in various international conferences.
