Parity Forwarding for Relay Networks
Fri, Jul 17, 2009 @ 11:00 AM - 12:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Peyman Razaghi,
Ph.D. candidate at University of TorontoAbstract: A relay is an intermediate communication device to assist the communication between a source node and a destination node. In this talk, we introduce a relaying strategy for multiple-relay networks called parity forwarding. We begin with the classic single-relay channel and develop a coding structure called bilayer LDPC coding to implement the bin-and-forward scheme of the classic decode-and-forward (DF) method. For DF, it is shown that binning is equivalent to generating parities, hence the name parity forwarding is suggested. For a multiple-relay channel with a single source and a single destination, we introduce a class of parity forwarding protocols in which relays send parity messages for the source message or the messages of other relays. We show that the proposed parity forwarding scheme improves the achievable DF rate and is capacity achieving for new types of degraded multiple-relay networks and improves previous achievable DF rates. Finally, we consider a network consisting of two interfering senders, two destinations, and a single relay. For additive channels, we show that in the asymptotic case where the receiver noise is negligible as compared to interference, a binning strategy which does not require decoding at the relay is asymptotically optimal.Biography: Peyman Razaghi has received his B.Sc.

Subthreshold Source-Coupled Circuit Design for Ultra-Low-Power Applications
Mon, Jul 20, 2009 @ 11:00 AM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Yusuf Leblebici (École Polytechnique Fédérale de Lausanne)Abstract:
In this talk, a novel approach is presented for
implementing ultra-low-power digital components
and systems using source-coupled logic (SCL)
circuit topology, operating in weak inversion
(subthreshold) regime. Minimum size pMOS
transistors with shorted drain-substrate
contacts are used as gate-controlled, very high
resistivity load devices. Based on the proposed
approach, the power consumption and the
operation frequency of logic circuits can be
scaled down linearly by changing the tail bias
current of SCL gates over a very wide range
spanning several orders of magnitude, which is
not achievable in subthreshold CMOS circuits.
Measurements in conventional 0.18um CMOS
technology show that the tail bias current of
each gate can be set as low as 10 pA, with a
supply voltage of 300 mV, resulting in a
power-delay product of less than 1 fJ
(Femto-Joule) per gate. Fundamental circuits
such as ring oscillators and frequency dividers,
as well as more complex digital blocks such as
parallel multipliers designed by using the STSCL topology will be presented.Speaker Biography:Yusuf Leblebici received his Ph.D. degree in

How to Explore a Fast-Changing World (Cover Time of a Simple Random Walk on Evolving Graphs)
Mon, Jul 27, 2009 @ 11:00 AM - 12:00 AM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Abstract.
Motivated by real world networks and use of algorithms based on random walks on
these networks we study the simple random walks on dynamic undirected graphs
with fixed underlying vertex set, i.e., graphs which are modified by inserting or
deleting edges at every step of the walk. We are interested in the expected time
needed to visit all the vertices of such a dynamic graph, the cover time, under the
assumption that the graph is being modified by an oblivious adversary. It is well
known that on connected static undirected graphs the cover time is polynomial in
the size of the graph. On the contrary and somewhat counter-intuitively, we show
that there are adversary strategies which force the expected cover time of a simple
random walk on connected dynamic graphs to be exponential. We relate this result
to the cover time of static directed graphs. In addition we provide a simple
strategy, the lazy random walk, that guarantees polynomial cover time regardless
of the changes made by the adversary.

SINR Diagrams: Towards Algorithmically Usable SINR Models of Wireless Networks
Tue, Jul 28, 2009 @ 11:00 AM - 12:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Abstract:
The rules governing the availability and quality of connections in a wireless network are
described by physical models such as the signal-to-interference & noise ratio (SINR) model. For
a collection of simultaneously transmitting stations in the plane, it is possible to identify a
reception zone for each station, consisting of the points where its transmission is received
correctly. The resulting SINR diagram partitions the plane into a reception zone per station and
the remaining plane where no station can be heard. SINR diagrams appear to be fundamental to
understanding the behavior of wireless networks, and may play a key role in the development of
suitable algorithms for such networks, analogous perhaps to the role played by Voronoi diagrams
in the study of proximity queries and related issues in computational geometry. So far, however,
the properties of SINR diagrams have not been studied systematically, and most algorithmic
studies in wireless networking rely on simplified graph-based models such as the unit disk graph
(UDG) model, which conveniently abstract away interference-related complications, and make it
easier to handle algorithmic issues, but consequently fail to capture accurately some important
aspects of wireless networks. The current paper focuses on obtaining some basic understanding
of SINR diagrams, their properties and their usability in algorithmic applications. Specifically,
based on some algebraic properties of the polynomials defining the reception zones we show that
assuming uniform power transmissions, the reception zones are convex and relatively wellrounded.
These results are then used to develop an efficient approximation algorithm for a
fundamental point location problem in wireless networks.

Image Representation, Matching, and Recognition Using Invariant Region Descriptors
Thu, Jul 30, 2009 @ 10:30 AM - 11:30 AM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker :Professor Zen Chen,
National Chiao-Tung UniversityAbstract: In 3D computer vision a scene or object in the real world can be characterized by multiple views imaged under different viewpoints and illuminations. The spatial and temporal relationships across these views are important to scene analysis and understanding. The local features are generally more robust to viewpoint change than the global features. The region feature design must take these into consideration, too. In the talk, topics related to local image representation, matching, and recognition under the geometric and photometric variations are addressed. First, a number of popular region descriptors will be reviewed and a new image descriptor, called the Zernike moment (ZM) phase, is to be introduced. The discriminative power of the new ZM phase descriptor is compared with five major existing region descriptors based on the precision-recall criterion. The experimental results involving more than 15 million region pairs indicate the proposed ZM phase descriptor has, overall speaking, the best performance under the common photometric and geometric transformations. Second, the proposed ZM phase descriptor is extended to present a new recognition method of logos imaged by the mobile phone cameras. The logo recognition can be incorporated with mobile phone service tools for use in enterprise identification, corporate website access, traffic sign reading, security check, and the related applications. Third, the one-to-one correspondence matching of feature points and its application to view registration will be addressed. We take advantage of preprocessing of the reference image offline to gather the important statistics for guiding view registration. Finally, an online registration process is presented to estimate a transformation matrix to overlay the reference image over a sensed imageBio: Prof. Zen Chen is Professor of Computer Science at National Chiao Tung University, Hsin-Chu, Taiwan.
