Algebraic Symmetries of Digital Signal Processing
Thu, Feb 07, 2013 @ 10:00 AM - 11:00 AM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Shamgar Gurevich, University of Wisconsin - Madison
Talk Title: Algebraic Symmetries of Digital Signal Processing
Abstract: We will explore basic algebraic symmetries of spaces of sequences that are used in digital signal processing (DSP). There are two types of symmetries: (1) The Heisenberg (after Werner Heisenberg) symmetries, which generalize the time-shift and frequency-shift operators. (2) The Weil (after Andrei Weil) operators which generalize the discrete Fourier transform (DFT). We will look on two applications: (I) Construction of the Heisenberg (Chirp) sequences---which are commonly used in radar systems---and relations among them. (II) Efficient calculation of the Radar Ambiguity Function on a general line in the discrete time-frequency plane. These applications will be used by Alexander Fish in his lecture "The Cross Method for Multi-Target Radar Detection".
The lecture is part from a joint work with: Alexander Fish (Sydney), Akbar Sayeed (EE, Madison), Oded Schwartz (EECS, Berkeley).
Biography: Shamgar Gurevich is a faculty in the mathematics department of the University of Wisconsin Madison.

The Cross Method for Multi-Target Radar Detection

Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Alexander Fish, University of Sydney
Talk Title: The Cross Method for Multi-Target Radar Detection
Abstract: We would like to know the distances to moving objects and their velocities. The radar system is built to fulfill this task. The radar transmits a waveform S which bounds back from the objects and the echo R is received. In practice we can work in the digital model, namely S and R are sequences of N complex numbers.
THE RADAR PROBLEM IS: Design S, and an effective method of extracting, using S and R, the distances and velocities of all targets.
In many applications the current sequences S which are used are pseudo-random and the algorithm they support takes O(N2logN) arithmetic operations. In the lecture we will introduce the Heisenberg sequences, and a much faster detection algorithm called the Cross Method. It solves the Radar Problem in O(NlogN+m2) operations for m objects.
This is a joint work with Shamgar Gurevich (Math, Madison), Akbar Sayeed (EE, Madison), Kobi Scheim (General Motors, Israel), Oded Schwartz (EECS, Berkeley)

Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: TBA, TBA
Talk Title: TBA
Series: EE598 Seminar Course
Abstract: Weekly seminars given by researchers in academia and industry including senior doctoral students in EE, CS and ISI covering current research related to parallel and distributed computation including parallel algorithms, high performance computing, scientific computation, application specific architectures, multi-core and many-core architectures and algorithms, application acceleration, reconfigurable computing systems, data intensive systems, Big Data and cloud computing.
Biography: Prerequisite: Students are expected to be familiar with basic concepts at the level of graduate level courses in Computer Engineering and Computer Science in some of these topic areas above. Ph.D. students in Electrical Engineering, Computer Engineering and Computer Science can automatically enroll. M.S. students can enroll only with permission of the instructor. To request permission send a brief mail to the instructor in text format with the subject field ââ¬ÅEE 598ââ¬Â. The body of the mail (in text format) should include name, degree objective, courses taken at USC and grades obtained, prior educational background, and relevant research background, if any.
Requirements for CR:
1. Attending at least 10 seminars during the semester
There will be a sign-in sheet and a sign-out sheet at every seminar. All students must sign-in (before 2:00pm) and sign-out (after 3:00pm). The sign-in sheet will not be available after 2:00pm, and the sign-out sheet will not be available before 3:00pm.
2. Submitting a written report for at least 5 seminars
The written report for each seminar must be 1-page single line spaced format with font size of 12 (Times) or 11 (Arial) without any figures, tables, or graphs. The report must be submitted no later than 1 week after the corresponding seminar, and must be handed only to the instructor either on the seminar times or during office hours. Late reports will not be considered.
The report must summarize studentââ¬â¢s own understanding of the seminar, and should contain the following:
- Your name and submission date [1 line]
- Title of the seminar, name of the speaker, and seminar date [1 line]
- Background of the work (e.g., applications, prior research, etc.) [1 paragraph]
- Highlights of the approaches presented in the seminar [1-2 paragraphs]
- Main results presented in the seminar [1-2 paragraphs]
- Conclusion (your own conclusion and not what was given by the speaker) [1 paragraph]
Reviewing papers related to the topic of the seminar, and incorporating relevant findings in the
reports (e.g., in the conclusion section) is encouraged. In such cases, make sure to clearly indicate
the reference(s) used to derive these conclusions.

EE 598: ELECTRICAL ENGINEERING RESEARCH SEMINAR 4
Thu, Feb 07, 2013 @ 02:00 PM - 03:00 PM

Conferences, Lectures, & Seminars
Speaker: Jong-Kook Kim, Associate Professor, Korea University - School of Electrical and Computer Engineering
Talk Title: Energy Aware High Performance Computing
Series: EE598 Seminar Course
Abstract: Power or Energy usage for various systems became an issue because of cost and efficiency. As the goal of advancing or enhancing a computing system is to increase or enhance the performance, it is not enough just to decrease the power or energy usage. Therefore, while trying to minimize the power usage the performance of the system must be upgraded. There are many environments or systems that must consider both energy and performance for enhancement at the same time. Distributed mobile computing is one such environment where computing resources are mobile, connected wirelessly, have limited battery power, and may be heterogeneous from one another. A multi-core chip multiprocessor can be another such system that may need an intelligent method to reduce the energy usage while also trying to enhance performance.
Biography: Jong-Kook Kim is currently an Associate Professor at Korea University, Seoul Korea. He received his M.S. and Ph.D. degrees in electrical and computer engineering from Purdue University in May 2000 and August 2004, respectively. He received his B.S. degree in electronic engineering from Korea University, Seoul, Korea in 1998. His research interests include heterogeneous distributed computing, real-time mobile computing, computer architecture, performance measures, resource management, evolutionary heuristics, energy-aware computing, and distributed compilers. He is a member of the IEEE, IEEE Computer Society, and ACM.
