Preface
Recently, mobile communication services are penetrating into our society at an ex-
plosive growth rate. All of the current communication systems have adopted digital
technology. Nowadays, the demand for various wideband services such as high-speed
Internet access and video/high-quality image transmission, is increasing. The third-
generation mobile communication system has been, designed to support wideband
services with the same quality as the fi xed networks. The wireless communication sys-
tems are expected to play a more important role in providing portable access to future
information services. The demand for new services to support Internet and advanced
video applications presents the key technical challenges, i.e., multimedia access re-
quires high-bandwidth and low-latency network connections for many users, mobility
requires adaptation to time varying channel conditions and portability imposes severe
constraints on receiver size and power consumption.
Physical limitations on wireless channels impose huge challenges on reliable com-
munication. Bandwidth limitations, propagation loss, noise and interference make the
wireless channel a narrow pipe that does not readily accommodate rapid fl ow of data.
Thus, researchers aim to design systems that are suitable to operate in such channels,
in order to have high performance quality of service. Also, the mobility of the commu-
nication systems requires further investigation to reduce the complexity and the power
consumption of the receiver.
This book presents new techniques that improve the performance of the communica-
tion system used for transmission of digital data over time varying channels such as
high frequency mobile channels. It aims to provide highlights of the current research
in the fi eld of wireless communication, and to off er a contribution to the recent advanc-
es in this fi eld. The subjects discussed in this work are very valuable to any researcher
in the communication fi eld not only to researchers in the wireless related areas. The
twenty-six chapters cover a wide range of topics in wireless communication starting
with the channel characterization, the conventional and adaptive antenna design, net-
works coding, optical communication, Multi-Input Multi-Output (MIMO) systems,
system fabrication and design, vehicular technologies, and communication protocols.
X Preface
The editor would like to thank all of the authors for their valuable contributions in
