This paper covers the keynote address delivered by the
Chairman of the COST Action 285 at the Symposium. It outlines the
studies undertaken by the members of the Action with the objective of
enhancing existing modeling and simulation tools and to develop new ones
for research in Emerging multiservice telecommunication networks. The
paper shows how the scope of COST Action 285 has been enriched by the
contributions made at the Symposium.
Emerging technologies such as WiFi and WiMAX are profoundly changing the
landscape of wireless broadband. As we evolve into future generation wireless
networks, a primary challenge is the support of high data rate, integrated multi-
media type traffic over a unified platform. Due to its inherent advantages in
high-speed communication, orthogonal frequency division multiplexing (OFDM)
has become the modem of choice for a number of high profile wireless systems
(e.g., DVB-T, WiFi, WiMAX, Ultra-wideband).
Optical wireless communication is an Emerging and dynamic research and development
area that has generated a vast number of interesting solutions to very complicated
communication challenges. For example, high data rate, high capacity and minimum
interference links for short-range communication for inter-building communication,
computer-to-computer communication, or sensor networks. At the opposite extreme is
a long-range link in the order of millions of kilometers in the new mission to Mars
and other solar system planets.
Reliable and accurate positioning and navigation is critical for a diverse set of Emerging applications
calling for advanced signal-processing techniques. This book provides an overview of some of the
most recent research results in the field of signal processing for positioning and navigation, addressing
many challenging open problems.
Software Radio (SR) is one of the most important Emerging technologies for the
future of wireless communication services. By moving radio functionality into
software, it promises to give flexible radio systems that are multi-service, multi-
standard, multi-band, reconfigurable and reprogrammable by software.
Today’s radios are matched to a particular class of signals that are well defined
bytheircarrierfrequencies,modulationformatsandbandwidths.Aradiotransmitter
today can only up convert signals with well-defined bandwidths over defined center
frequencies, while, on the other side of the communication chain, a radio receiver
can only down convert well-defined signal bandwidths, transmitted over specified
carrier frequencies.
Driven by the desire to boost the quality of service of wireless systems closer to that afforded
by wireline systems, space-time processing for multiple-input multiple-output (MIMO)
wireless communications research has drawn remarkable interest in recent years. Excit-
ing theoretical advances, complemented by rapid transition of research results to industry
products and services, have created a vibrant and growing area that is already established
by all counts. This offers a good opportunity to reflect on key developments in the area
during the past decade and also outline Emerging trends.
Welcome to the world of wireless communications and the logical extension
to the broadband architectures that are Emerging as the future of the
industry. No aspect of communications will be untouched by the wireless
interfaces;no part of our working environment will be left untouched either.
As the world changes and the newer technologies emerge, we can expect to
see more in the line of untethered communications than in the wired inter-
faces.
Wireless communications, together with its applications and underlying technologies, is
among today’s most active areas of technology development. The very rapid pace of im-
provements in both custom and programmable integrated circuits for signal processing ap-
plications has led to the justfiable view of advanced signal processing as a key enabler of the
aggressively escalating capacity demands of Emerging wireless systems. Consequently, there
has been a tremendous and very widespread effort on the part of the research community
to develop novel signal processing techniques that can fulfill this promise.
This paper reviews key factors to practical ESD
protection design for RF and analog/mixed-signal (AMS) ICs,
including general challenges Emerging, ESD-RFIC interactions,
RF ESD design optimization and prediction, RF ESD design
characterization, ESD-RFIC co-design technique, etc. Practical
design examples are discussed. It means to provide a systematic
and practical design flow for whole-chip ESD protection design
optimization and prediction for RF/AMS ICs to ensure 1 st Si
design success.
Commercial energy storage has moved from the margins to the mainstream as it
fosters flexibility in our smarter, increasingly integrated energy systems. The
energy density, availability, and relatively clean fossil profile of natural gas ensure
its critical role as a fuel for heating and electricity generation. As a transportation
fuel, natural gas continues to increase its market penetration; much of this has been
enabled by Emerging developments in storage technology.
