Keynote Lecture 1
Next Generation CDMA Technologies for Futuristic Wireless Communications
  Hsiao-Hwa Chen
National Sun Yat-Sen University, Taiwan
Brief Bio:
Hsiao-Hwa Chen is currently a full Professor and was the founding Director of the Institute of Communications Engineering of the National Sun Yat-Sen University, Taiwan. He received BSc and MSc degrees from Zhejiang University, China, and PhD degree from University of Oulu, Finland, in 1982, 1985 and 1990, respectively, all in Electrical Engineering. He has authored or co-authored over 200 technical papers in major international journals and conferences, five books and several book chapters in the areas of communications, including the books titled "Next Generation Wireless Systems and Networks" (512 pages) and “The Next Generation CDMA Technologies” (468 pages), both published by John Wiley and Sons in 2005 and 2007, respectively. He has been an active volunteer for IEEE various technical activities for over 20 years. Currently, he is serving as the Chair of IEEE Communications Society Radio Communications Committee. He served or is serving as symposium chair/co-chair of many major IEEE conferences, including VTC, ICC, Globecom and WCNC, etc. He served or is serving as Associate Editor or/and Guest Editor of numerous important technical journals in communications. He is serving as the Editor (Asia and Pacific) for Wiley's Wireless Communications and Mobile Computing (WCMC) Journal and Wiley's International Journal of Communication Systems, etc. He is the founding Editor-in-Chief of Wiley’ Security and Communication Networks journal ( He is also an adjunct Professor of Zhejiang University, China, and Shanghai Jiao Tung University, China.
Future wireless communication systems should be operating mainly, if not completely, for burst data services carrying multimedia traffics. The need to support high-speed burst traffic has already posed a great challenge to all currently available air-link technologies based on either TDMA or CDMA. The current CDMA technology has been widely used in both 2G and 3G mobile cellular standards and it has been suggested that it is not suitable for high-speed burst-type traffic. There are many problems with current CDMA technology, such as its low spreading efficiency, interference-limited capacity and the need for precision power control, etc. This talk will address various important issues about the next generation CDMA technologies as a major air-link technology for futuristic wireless applications. In particular, it will cover two major topics: why we need the next generation CDMA technologies, and what is the next generation CDMA technology.
Keynote Lecture 2
The importance of Metrology in Wireless Communication Systems – From AM/FM to SDR Systems
  Nuno Borges Carvalho
Instituto de Telecomunicacoes / Universidade de Aveiro, Portugal
Brief Bio:
Nuno Borges Carvalho, was born in Luanda in 1972. He received the diploma and doctoral degrees in Electronics and Telecommunications Engineering from the Universidade de Aveiro, Aveiro, Portugal in 1995 and 2000 respectively. From 1997 to 2000 he was an Assistant Lecturer at the same University and a Professor since 2000. Currently he is an Associate Professor at the same University, and the scientific area coordinator of the wireless communications at Instituto de Telecomunicações. He has worked as a scientist researcher at the Instituto de Telecomunicações, and was engaged to different projects on nonlinear CAD, circuits and systems design and RF system integration. His main research interests include CAD for nonlinear circuits/systems, nonlinear distortion analysis in microwave/wireless circuits and systems and measurement of nonlinear phenomena, recently he has also been involved in design of dedicated radios and systems for newly emerging wireless technologies. In 2007 he was a visitor researcher at the North Carolina State University, and at the National Institute of Standards and Technology , NIST. Prof. Borges Carvalho is a member of the Portuguese Engineering Association and an IEEE Senior Member. He was the recipient of the 1995 University of Aveiro and the Portuguese Engineering Association Prize for the best 1995 student at the Universidade de Aveiro, the 1998 Student Paper Competition (third place) presented at the IEEE International Microwave Symposium, the 2000 IEE Measurement Prize. He is also the co-inventor of three registered national patents. He is a reviewer for several magazines including the IEEE Transactions on Microwave Theory and Techniques, IEEE Transactions on Cicuits and Systems, IEEE Transactions on Communications and IEEE Transactions on Intelligent Transportion Systems, as some International journals from the Institute of Physics. He is the webmaster and an active member of the IEEE MTT-11 Technical Committee, and the chair of the URSI-Portugal metrology committee. Dr. Borges Carvalho is co-author of the book “Intermodulation in Microwave and Wireless Circuits” from Artech House, 2003.
Metrology is a key point in the design and optimization of wireless communication networks, in this talk we will make a brief presentation of the metrology chain necessities from base-band to RF wireless communication scenarios. In this path we will address linear and nonlinear measurements strategies, from RF figures of merit to base band figures. Finally some recent developments referred to software radio activities will also be presented, explaining the new paradigms and envisioning the future of wireless metrology.
