Wireless multimedia communication systems (WMCSs) have become one
of the most important mediums for information exchange and the core communication
environment for business relations as well as for social interactions.
This is a rapidly evolving field with growing applications in science and
engineering. Millions of people all over the world use WMCSs for a plethora
of daily activities. As we move further into the information age, this rapid
advancement will continue in all aspects of WMCSs technologies.
Wireless technologies affect research fields in several disciplines. At
the same time, wireless research has also benefited from ideas developed
in other fields. How to effectively utilize the interdisciplinary research
ideas to develop more efficient wireless technologies opens a new thread of
research and design. After many years of research activities related to the
optimization of the physical layer of radio networks, the focus is shifting in
part toward system and applications level engineering and optimization for
an improved performance of wireless multimedia communications. New
topics are introduced, most of them not only to incrementally improve
current systems but also to provide superior capacity, spectral efficiency,
and flexible operation to next generation wireless systems (NGWSs). This
can be achieved by extending the system bandwidth and pushing up the
transmission rate by coordinating radio resources across adjacent cells for
reduced interference in dense reuse of cellular networks, and by introducing
mesh networking components and smart antenna technology for spatial
multiplex´┐Żbased transmission.
