报告摘要：

In this overview talk, we will review three different classes of microphone arrays for various applications. The first array used four uniformly-spaced hearing aid microphones to perform a steerable array based on the maximum-energy criterion. A system implemented with a DSP processor board collected various experimental data in an anechoic chamber and a regular room for hearing aid applications. The second array used randomly distributed microphones to perform wideband beamforming based on a maximum eigenvector array for vehicle detection, localization, and signal enhancement. The third array was based on the Approximate Maximum-Likelihood criterion to estimate single or multiple acoustic sources for near-field localization and far-field direction-of-arrival estimations. This array was capable of various beamforming and nulling operations. Several wired wireless experimental arrays have been implemented for various applications. In particular, we will present some recent bio-complexity applications to field monitoring, detection, and localization of woodpecker (a North American bird) and marmot (a wild ground squirrel).  Various sound demonstrations will be given.

姚琨教授简介：

Kung Yao received the B.S.E. (Summa Cum Laude), M.A. and Ph.D. degrees in electrical engineering all from Princeton University, Princeton, N.J. He was a NAS-NRC Post-Doctoral Research Fellow at the University of California, Berkeley. Presently, he is a Distinguished Professor in the Electrical Engineering Department at UCLA. In 1969, he was a Visiting Assistant Prof. at the Massachusetts Institute of Technology. In 1973-74, he was a Visiting Associate Prof. at the Eindhoven University of Technology. In 1985-1988, he served as an Assistant Dean of the School of Engineering and Applied Science (SEAS) at UCLA. In 2001-2003, he served as the Chair of the Faculty Executive Committee (legislature body of the faculty members) of SEAS.

His research and professional interests include sensor array system, digital communication theory and system, smart antenna and wireless radio system, communications theory and system, digital and array signal and array processing, systolic and VLSI algorithms, architectures and systems, radar system, satellite system, and simulation. He has published over 300 journal and conference papers. Dr. Yao received the IEEE Signal Processing Society's 1993 Senior Award in VLSI Signal Processing. He is the co-editor of a two volume series of an IEEE Reprint Book on "High Performance VLSI Signal Processing," 1997. He is the co-author of two books, “Detection and Estimation” and "Processing and Algorithms in Communication and Radar Systems", under preparation for Cambridge Press.

He has served as Program Chair, Secretary, and Chair of the IEEE Information Theory Society in L.A. and served two terms as a member of the Board of Governors of the IEEE Information Theory Society. Dr. Yao was a member of the VLSI Technical Committee of the IEEE Signal Processing Society. He was also the Chair of the Technical Program and the General Chair of the 1990 and 1992 IEEE Workshop on VLSI Signal Processing. He has served as an Associate Editors for: IEEE Trans. on Information Theory; Probability in the Engineering and Informational Sciences; IEEE Trans. on Circuits and Systems; Journal of VLSI Signal Processing; Integration: the VLSI Journal; Eurasp Journal of Applied Signal Processing; and IEEE Transactions on Signal Processing. He has organized and chaired various sessions in communications, signal/array processing, VLSI, and wireless radio for IEEE and SPIE conferences. He is a Life Fellow of IEEE.

Dr. Yao is a member of UCLA NSF funded Center for Embedded Sensing Networking (CENS) and his research in recent years has been funded by NSF, DARPA, MURI, JPL, STM, UC-Discovery, and UC MICRO. He also has extensive practical system experiences in sensor networks, digital/satellite/wirless communication engineering, DSP, radar system, link budget analysis, and systolic and microphone array designs. He has worked or consulted for AT&T Bell Laboratories, NCR, SRI, TRW, Linknet, and Hughes Aircraft Company, and Raytheon Systems Company.
