报告题目：
Cognitive and Cooperative Communications for Future Wireless Systems

摘要:
Cognitive radio is an exciting emerging technology, which has the potential of dealing with the stringent requirement and scarcity of radio spectrum and promoting dynamic spectrum access by opportunistically sensing and exploiting the spectrum “holes”. In recent years, cooperative communication has been developed into a promising new technology that allows distributed terminals in a wireless network to collaborate through distributed transmission or signal processing means so as to realize a new form of space diversity in enhancing performance. In the context of cognitive radio system, cooperative transmission is envisioned to be able to bring along new direction and dimension to dramatically improve the spectrum utilization and efficiency. This talk will discuss the challenges facing future wireless systems and discuss some of the key enabling technologies with special emphasis on cognitive radio and cooperative communications, including cooperative spectrum sensing and detection, cognitive relay transmission, and adaptive modulation and coding for cognitive radio.

Pak-chung Ching received the B. Eng. (1st Class Honors) and Ph.D. degrees from the University of Liverpool, UK, in 1977 and 1981 respectively. From 1981 to 1982 he was Research Officer at the University of Bath, UK. In 1982, Prof. Ching returned to Hong Kong and joined the then Hong Kong Polytechnic as a lecturer. Since 1984, he has been with the Department of Electronic Engineering of the Chinese University of Hong Kong (CUHK), where he is currently Professor of Electronic Engineering. He was Department Chairman from 1995 to 1997, Dean of Engineering from 1997 to 2003 and Head of Shaw College from 2004 to 2008. He became Director of the Shun Hing Institute of Advanced Engineering in 2004. Beginning 1 August 2006, Prof. Ching assumes his new responsibility as Pro-Vice-Chancellor of CUHK.
Prof. Ching is very active in promoting professional activities, both in Hong Kong and overseas. He has served in different capacities at the Hong Kong Institution of Engineers (HKIE), and has been Council Member of the Institution of Electrical Engineers (IEE), and Member of the Technical Committee on Signal Processing Theory and Methods of the Institute of Electrical and Electronic Engineers (IEEE). He has been on the editorial board of a number of leading publications. He was Associate Editor for IEEE Transactions on Signal Processing (1997-2000), Associate Editor for IEE Signal Processing Letters (2001-2003), and Editor-in-chief for HKIE Transactions. He is also an Honorary Member of the editorial committee for Journal of Data Acquisition and Processing. He is a Fellow of IEE and HKIE, and was awarded the IEEE Third Millennium Award in 2000.
His current research interests include adaptive digital signal processing, time delay estimation and target localization, blind signal estimation and separation, automatic speech recognition, speaker identification/verification and speech synthesis, and advanced signal processing techniques for wireless communications. He has served as guest professor of Beijing University of Posts and Telecommunications, Huazhong University of Science and Technology, Southeast University, and Institute of Acoustics of the Chinese Academy of Science.
