Meet USC: Admission Presentation, Campus Tour, & Engineering TalkMon, Dec 10, 2012
Viterbi School of Engineering Undergraduate Admission
Receptions & Special Events
This half day program is designed for prospective freshmen and family members. Meet USC includes an information session on the University and the Admission process; a student led walking tour of campus and a meeting with us in the Viterbi School. Meet USC is designed to answer all of your questions about USC, the application process and financial aid. Reservations are required for Meet USC. This program occurs twice, once at 8:30 a.m. and again at 12:30 p.m. Please visit https://esdweb.esd.usc.edu/unresrsvp/MeetUSC.aspx to check availability and make an appointment. Be sure to list an Engineering major as your "intended major" on the webform!

On Positioning Algorithms that are Robust Against Non-Line-of-Sight Measurements

Talk Title: On Positioning Algorithms that are Robust Against Non-Line-of-Sight Measurements
Abstract: In this talk, we will discuss distance-based positioning, i.e., given a number of noisy distance measurements from nodes at fixed and known positions (anchor nodes), determine the position of one or several other nodes (target nodes). GPS and other global satellite navigation systems solve these type of problems. However, in non-line-of-sight conditions, distance measurements tend to suffer from large positive biases, which cause large position errors if not properly compensated for. We will present a number of positioning algorithms, based on Projection Onto Convex Sets (POCS), which are very robust against positive errors. In fact, if there are a few measurements with small errors, POCS-based algorithms can handle arbitrary large positive errors in arbitrarily many other measurements. The price to pay is less accuracy compared to conventional algorithms, such as nonlinear least squares, when there are no large positive errors.
Biography: Erik G. Ström (https://sites.google.com/site/erikgstrom/) received the M.S. degree from the Royal Institute of Technology (KTH), Stockholm, Sweden, in 1990, and the Ph.D. degree from the University of Florida, Gainesville, in 1994, both in electrical engineering. He accepted a postdoctoral position at the Department of Signals, Sensors, and Systems at KTH in 1995. In February 1996, he was appointed Assistant Professor at KTH, and in June 1996 he joined Chalmers University of Technology, Gothenburg, Sweden, where he is now a Professor in Communication Systems since June 2003. Dr. Ström currently heads the Division for Communications Systems, Information Theory, and Antennas at the Department of Signals and Systems at Chalmers and leads the competence area Sensors and Communications at the traffic safety center SAFER, which is hosted by Chalmers. His research interests include signal processing and communication theory in general, and constellation labelings, channel estimation, synchronization, multiple access, medium acccess, multiuser detection, wireless positioning, and vehicular communications in particular. Since 1990, he has acted as a consultant for the Educational Group for Individual Development, Stockholm, Sweden. He is a contributing author and associate editor for Roy. Admiralty Publishers FesGas-series, and was a co-guest editor for the Proceedings of the IEEE special issue on Vehicular Communications (2011) and the IEEE Journal on Selected Areas in Communications special issues on Signal Synchronization in Digital Transmission Systems (2001) and on Multiuser Detection for Advanced Communication Systems and Networks (2008). Dr. Ström was a member of the board of the IEEE VT/COM Swedish Chapter 2000--2006. He received the Chalmers Pedagogical Prize in 1998 and the Chalmers Ph.D. Supervisor of the Year award in 2009.
