Finite-Field Multi-Carrier Modulation
Thu, Sep 01, 2011 @ 11:00 AM - 12:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Lin Luo, University of South Australia (UniSA), Australia
Talk Title: Finite-Field Multi-Carrier Modulation
Abstract: Multicarrier modulation, e.g. OFDM, has been endorsed by leading standards in both wireline and wireless high speed digital communications. However, the large dynamic range of an OFDM signal causes an inefficient transmit radio frequency circuitry and distorted signal modulation. We introduce the concept of processing signals in a finite field and replace the DFT by finite-field transforms, which reduce the OFDM Peak-to-Average Power Ratio (PAPR) significantly to the range of a finite alphabet set. Most importantly, the system model can be treated as a block code that is corrupted by the additive channel noise, which means the new system has inherent error control capability. Furthermore, processing signals in a finite field not only make modulation part of error correcting coding, but also design codes by exploiting the philosophy of modulation. We will study a framework for multi-carrier modulation with finite-field transforms.
Biography: Dr. Lin Luo received B.E. in Electronic Engineering from University of Electronic Science and Engineering in China (UESTC) in 2002, M.E. in Telecommunications Engineering from The University of Melbourne in 2004, and a Ph.D. in Telecommunications Engineering from The Australian National University (ANU) in 2009. Since June 2009, he has been a Research Fellow at the Institute for Telecommunications Research (ITR), University of South Australia (UniSA), Australia. His current research interests include multi-carrier and single-carrier systems, green communications, MIMO, and vehicle-to-vehicle communications.

Viterbi School of Engineering Student Organizations
Student Activity
Come out to SWE's first general meeting and learn what SWE can do for you this year! We will be going over our calendar of events, introducing the new leaders of SWE, as well as making time to network with new friends and reunite with some old SWEsters. There will be pizza and of course, some great SWE bonding time! Hope to see you there!

TOCHKA: A Screening and Discussion with the Artists
Thu, Sep 01, 2011 @ 07:00 PM - 09:00 PM
USC Viterbi School of Engineering
Receptions & Special Events
The Japanese artist team TOCHKA, featuring artists Kazue Monno and Takeshi Nagata, will present a screening and discussion of their work. Their PIKA PIKA workshops have spawned a DIY âlightning doodleâ subculture that has gone viral! Their presentation will explore pop-up art in public spaces, low-tech choices in a high-tech world and cross-cultural communication aided by YouTube and social media. TOCHKAâs goal is to bring joy and inspire people to work together across cultural, ethnic and linguistic differences.
About the Artists
Takeshi Nagata and Kazue Monno, a.k.a. TOCHKA, have been creating music videos, short animated films and comics for about ten years. After graduating from the Kyoto University of Art and Design in 2000, their artistic collaboration began with works of frame-by-frame clay animation and hand-drawn short animated movies. From there the duo shifted toward an experimental approach to computer graphicsâbased imagery. They are best known for their light-animation projects. Using simple flashlights, LEDs and long exposures with a digital still camera at night, they create colorful, playful doodle animations. They have received numerous awards and have screened their work at major animation festivals, including the Mostra-Mundo Festival in Brazil, the Annecy International Animation Festival in France, the New York Film Festival, the Platform International Animation Festival in the United States and the Japan Media Arts Festival.
Organized by Lisa Mann, Trixy Sweetvittles and Richard Weinberg (Animation & Digital Arts).
