Professor Francis C.M. Lau, The Hong Kong Polytechnic University, Hong Kong

Title: Chaotic Communications: The Past, The Present and The Future

 

Abstract:

A tiny difference can sometimes make significant changes. Such events that are occurring around us all the time are called chaos. Yet, chaos theory started only in the 1960s. In this presentation, we introduce chaotic phenomenon and its characteristics. We also discuss the benefits of using chaotic signals in transmitting messages and the development of different types of chaotic communication systems, one of which became one of the candidates for use in ultra-wideband communication systems. Finally, we provide future research directions in this area.

Professor Suzanne LESECQ, CEA-LETI, MINATEC Campus, France

Title: Local (V,T) estimation in integrated circuits using a set of statistical tests

 

Abstract:

Mobile platforms need ever-increasing computational performances under stringent energy consumption limitation mainly due to the battery lifespan.  An  optimal  operating  point  is  obtained  thanks  to  a  compromise  between  performance  and  power consumption. For distributed architectures (e.g. MultiProcessor System on Chip), the supply voltage  and  the  operating  frequency  of  each  processing  element  are  dynamically  tuned  to reach efficient performance/power consumption trade-offs. To increase the performance of each “actuator”, the physical state (e.g.  the  current  supply  voltage  and  temperature)  of  the integrated  circuit  must  be  monitored  to  locally  adapt  the  control  parameters.  During this keynote, we will present a new estimation method based on statistical tests to estimate the supply  voltage  and  the  temperature  of  a  local  area  in  an  integrated  circuit.  Standard ring  oscillators  buried  in  the  chip provide the raw measurements that are fused to estimate the IC physical state. The  results  presented  here  have  been  developed  in  cooperation  between  the  CEA-LETI (Mrs E. Beigné, Mr. L. Vincent, Dr. S. Lesecq), Grenoble, France and the LIRMM, Montpellier, France (Dr. Ph. Maurines).

Professor Yasutaka Ogawa, Hokkaido University, Japan

Title: Development of Space-Domain Signal Processing for Wireless Communications

 

Abstract:

Multiple-input multiple-output (MIMO) systems have been extensively studied over the last decade because they provide high data-rate transmission without increasing the frequency bandwidth. They have already been in practical use in wireless local area networks (WLANs) and the long term evolution (LTE) of cellular networks. A MIMO system is one of the applications of space-domain signal processing. On the other hand, an adaptive antenna can suppress interference and realize a diversity effect. An adaptive antenna is a simpler application of space-domain signal processing.

In this talk, we will share the basic concept of the space-domain signal processing with the audience. Then, this presentation will introduce the space division multiple access (SDMA) for the Personal Handy-phone System (PHS) using the adaptive antenna. Furthermore, we will discuss some important features of MIMO systems.

Ogawa

Yasutaka Ogawa received the B.E., M.E. and Ph.D. degrees from Hokkaido University, Sapporo, Japan. Since 1979, he has been with Hokkaido University, where he is currently a professor of the Graduate School of Information Science and Technology. During 1992–1993, he was with ElectroScience Laboratory, the Ohio State University, U.S.A., as a visiting scholar, on leave from Hokkaido University.

His professional expertise encompasses super-resolution estimation techniques, applications of adaptive antennas for mobile communication, multiple-input multiple-output (MIMO) techniques, and measurement techniques. He proposed a basic and important technique for time-domain super-resolution estimation for electromagnetic wave measurement such as antenna gain measurement, scattering/diffraction measurement, and radar imaging. Also, his expertise and commitment to advancing the development of adaptive antennas contributed to the realization of space division multiple accesses (SDMA) in the Personal Handy-phone System (PHS).

He received the Yasujiro Niwa outstanding paper award in 1978, the young researchers’ award of Institute of Electronics, Information and Communication Engineers of Japan (IEICE) in 1982, the best paper award from IEICE in 2007, TELECOM system technology award from the Telecommunications Advancement Foundation of Japan in 2008, and the best magazine paper award in 2011 from IEICE Communications Society. He also received the Hokkaido University Commendation for excellent teaching in 2012.

He is a chairperson of the IEICE Hokkaido Section and the IEEE Sapporo Section. He is a Fellow of the IEICE and IEEE.

 


 

Professor Raymond Yeung, Institute of Network Coding, The Chinese University of Hong Kong
Title: Network Coding: An Overview
Abstract:
In recent years, network coding has generated much interest in information theory, coding theory, networking, wireless communications, cryptography, and computer science.  Consider a point-to-point communication network on which a number of information sources are to be mulitcast to certain sets of destination nodes.  The problem is to characterize the maximum possible throughputs.  Contrary to one's intuition, network coding theory reveals that it is in general not optimal to regard the information to be multicast as a "fluid" that can simply be routed or replicated.  Rather, by employing coding at the nodes, bandwidth can in general be saved.  In this talk, we will give an overview of the recent developments in the field and discuss how they can eventually lead to a new information infrastructure.
