About Me

Yeheskel Bar-Ness received the B.Sc. and M.Sc. degrees in electrical engineering from the Technion, Haifa, Israel, and the Ph.D. degree in applied mathematics, Brown University, Providence, RI.

Currently, he is a Distinguished Professor of Electrical and Computer Engineering and Foundation Chair of Center for Communication and Signal Processing Research (CCSPR) at the New Jersey Institute of Technology (NJIT), Newark. He worked for the Nuclear Medicine Department, Elscint Ltd., Haifa, as a Chief Engineer in the field of control, and image and data processing. In 1973, he joined the School of Engineering, Tel-Aviv University, where he held the position of Associate Professor of Control and Communications. Between September 1978 and September 1979, he was a Visiting Professor with the Department of Applied Mathematics, Brown University. He was on leave with the University of Pennsylvania and Drexel University, Philadelphia, PA. He came to NJIT from AT&T Bell Laboratories in 1985. Between September 1993 and August 1994, he was on sabbatical with the Telecommunications and Traffic Control Systems Group, Faculty of Electrical Engineering, Delft University of Technology, Delft, The Netherlands. Between September 2000 and August 2001, he was on sabbatical at Stanford University, Stanford, CA. His current research interests include adaptive multiuser detection, array processing and interference cancellation, and wireless mobile and personal communications.

Dr. Bar-Ness was an Area Editor for IEEE TRANSACTIONS ON COMMUNICATIONS (Transmission Systems) and Editor for Adaptive Processing Systems. He is the Founder and Editor-in Chief for IEEE COMMUNICATIONS LETTERS. He also was Editor for Wireless Personal Communications, an international journal. He was Chairman of the Communication Systems Committee, and a Vice Chair of the Communications Theory Committee of the IEEE Communication Society. He served as the General Chair of the 1994 and 1999 Communication Theory Mini-Conference. He was also the Technical Chair for the IEEE Sixth International Symposium on Spread Spectrum Techniques and Applications (ISSSTA 2000). He is a recipient of the Kaplan Prize (1973), which is awarded annually by the government of Israel to the ten best technical contributors, of the IEEE Communication Society Publication Exemplary Service Award, and was selected as NJ 2006 "Inventor of the year" recognized for "System and method to enhance wireless/mobile communication".

ECE 757

Prerequisites: ECE 742, equivalent, or instructor approval. 

Due to the increasing demand for personal, mobile and indoor communication systems in recent years, wireless communication has become a very hot topic within the filed of communication. Wireless communication is projected to become a multi-billion-dollar industry in the next few years. Two generations of systems already exist. The third generation is under research and expected to be standardized very shortly. The topic is of interest to a few of the faculty at the Center for Communications and Signal Processing Research. Thus is is natural to have this course as part of the graduate course curricula. Course Outline
