UNIVERSITY OF SOUTHERN CALIFORNIA VITERBI SCHOOL OF ENGINEERING MING HSIEH DEPARTMENT OF ELECTRICAL ENGINEERING 2011 RESEARCH BOOK First Annual Electrical Engineering Research Festival sponsored by the Ming Hsieh Institute April 29, 2011 http://mhi.usc.edu WELCOME FROM THE MING HSIEH INSTITUTE DIRECTOR April 29, 2011 On behalf of the Ming Hsieh Institute (MHI), my co-directors, Hossein Hashemi, Bhaskar Krishnamachari and I are pleased to welcome you to review the outstanding research of our Ph.D. students and postdoctoral scholars in the Ming Hsieh Department of Electrical Engineering. The Ming Hsieh Institute in the Ming Hsieh Department of Electrical Engineering was launched in July 2010, after a generous endowment gift of $35 million dollars from Mr. Ming Hsieh, an alumnus of the department. One of the main goals of the institute is to position the Electrical Engineering Department at the forefront in thought leadership in the world in the area of electrical engineering, and specifically in the development of intelligent technologies to empower mankind. The vision for our Institute is to create a vibrant intellectual environment at USC where world-class researches in Electrical Engineering and related fields can come together and engage in the development of new ideas. The first annual Electrical Engineering Research Festival that we are hosting today is a step in this direction. We hope you enjoy your day and have great conversations with our students and faculty regarding their research. To learn more about the Ming Hsieh Institute and its future events, please visit us at http://mhi.usc.edu. We thank you for your participation today, and hope for your continued engagement and participation in the institute’s activities. Sincerely, Shrikanth S. (Shri) Narayanan Andrew Viterbi Professor of Engineering; Professor of Electrical Engineering, Computer Science, Linguistics and Psychology 2011 USC EE Research Book Welcome from the Ming Hsieh Institute Director 2 MESSAGE FROM THE MING HSIEH ELECTRICAL ENGINEERING DEPARTMENT CHAIRS Welcome to the Ming Hsieh Department of Electrical Engineering! USC began teaching electrical engineering more than a century ago, when the field was widely considered a subset of physics. Today our work is vitally important and critical to the advancement of the information age. As our department charges into its second century of excellence, we are defining the forefront of research in a number of important areas. These include: circuits; antennas; wireless communications; bio-signal processing; computer architecture; very large-scale integration and computer-aided design; computer networks; control systems; high-speed switching architectures; signal, image and multimedia processing; nanotechnology; optical communications; photonics; and quantum information processing. Among our distinguished faculty are the visionary leaders of the university, including USC President Max Nikias and President Emeritus Steven Sample. We are also proud that Qualcomm and Linkabit co- founder Andrew J. Viterbi is a faculty member. In 2008, he received the National Medal of Science and was a Laureate of the Millenium Technology Prize Foundation of Finland, and in 2010, he received the IEEE Medal of Honor. The School of Engineering school bears his name. Our department is also home to thirteen other National Academy of Engineering members. We’re proud of our department’s distinguished history and our vital and innovative faculty and Ph.D. students. Please take a few minutes to explore some of the highlights of their work, compiled in this Research Book. Alexander A. Sawchuk Eun Sok Kim Leonard M.
