Interference Alignment and Degrees of Freedom of Wireless Networks
Fri, Oct 19, 2007 @ 11:00 AM - 12:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
SPEAKER: Professor Syed Jafar, University of California, IrvineABSTRACT: The talk will present new insights into the capacity of fully connected wireless networks with finite number of nodes through capacity approximations that are accurate to within a bounded constant for all SNR. While the best known outerbound for the K user interference channel states that there cannot be more than K/2 degrees of freedom, it has been conjectured that in general the constant interference channel with any number of users has only one degree of freedom. In this talk, we show that K/2 degrees of freedom can be achieved by channel design, i.e. if the nodes are allowed to choose the best constant, finite and non-zero channel coefficient values. Even if channel coefficients cannot be controlled by the nodes but are selected by nature, i.e., randomly drawn from a continuous distribution, the total number of spatial degrees of freedom for the K user interference channel is almost surely K/2 per orthogonal time and frequency dimension. In other words we will show how to achieve K/2 interference free channels per time and frequency dimension in a K user interference network of single antenna nodes. Thus, only half the spatial degrees of freedom are lost due to distributed processing of transmitted and received signals on the interference channel. We will also characterize the benefits of cognitive message sharing among nodes from a degrees of freedom perspective.BIO: Syed Ali Jafar received the B. Tech. degree in Electrical Engineering from the Indian Institute of Technology (IIT), Delhi, India in 1997, the M.S. degree in Electrical Engineering from California Institute of Technology (Caltech) , Pasadena USA in 1999, and the Ph.D. degree in Electrical Engineering from Stanford University, Stanford, CA USA in 2003. His industry experience includes positions at Lucent Bell Labs , Qualcomm Inc. and Hughes Software Systems . He is currently an Assistant Professor in the Department of Electrical Engineering and Computer Science at the University of California Irvine, Irvine, CA USA. His research interests include multiuser information theory and wireless communications. Dr. Jafar received the NSF CAREER award and the UC Irvine Engineering Faculty of the Year award in 2006. Dr. Jafar serves as the Editor for Wireless Communication Theory and CDMA for the IEEE Transactions on Communications.Host: Giuseppe Caire, caire@usc.edu

Geological Perspectives of Global Climate Change – An Update
Fri, Oct 19, 2007 @ 01:00 PM - 02:00 PM
Sonny Astani Department of Civil and Environmental Engineering
Conferences, Lectures, & Seminars
Speaker:Dr. Lee C. Gerhard,
Principal Geologist,
Kansas Geological SurveyAbstract:Objective evaluation of recent data suggests that review of the popular anthropogenic climate change control hypothesis is required. One response to new conflicting data has been to argue that the human component is operative only over the last thirty years, thus obviating the need to explain discrepancies between carbon dioxide buildup and temperature variations over the last century and beyond.Review will focus upon the answers to several questions. Is there any unequivocal data that support anthropogenic control of climate change? Is there any significant difference in the behavior of current climate compared to past climate? Is the range of current climate change greater than past climate change? Are sea levels and weather patterns significantly different from the recent past? Can the large-scale climate models be tested against recorded history? Are the data used accurate and are data series length adequate to form conclusions? What natural forces can explain temperature variations?Previously the anthropogenic hypothesis has not been testable. Two very recent statements have argued that future annual temperatures will exceed the 1999 (1934) maximum 50% of the time, and that sea levels will rise about one meter in the next approximately one hundred years owing to climate warming, no matter the cause. In contrast, there have been predictions of imminent cooling by 2020 owing to solar intensity decline (solar cycle 25), and one prediction of a cooling cycle that will last for decades. While neither statement tests the anthropogenic hypothesis, they are global warming statements that can be tested against global cooling or stabilityClimate continues to change as it always has. Much alarm has been raised about the impacts of climate change, without consideration of current climate in its historical context. Do we live in the ideal climate?
