The third generation (3G) mobile communication system is the next big thing
in the world of mobile teleCOMMUNICATIONs. The first generation included
analog mobile phones [e.g., Total Access COMMUNICATIONs Systems
(TACS), Nordic Mobile Telephone (NMT), and Advanced Mobile Phone
Service (AMPS)], and the second generation (2G) included digital mobile
phones [e.g., global system for mobile COMMUNICATIONs (GSM), personal
digital cellular (PDC), and digital AMPS (D-AMPS)]. The 3G will bring
digital multimedia handsets with high data transmission rates, capable of
providing much more than basic voice calls.

Wireless is one of the most rapidly developing technologies in our time, with dazzling
new products and services emerging on an almost daily basis. These developments present
enormous challenges for COMMUNICATIONs engineers, as the demand for increased wireless
capacity grows explosively. Indeed, the discipline of wireless COMMUNICATIONs presents
many challenges to designers that arise as a result of the demanding nature of the physical
medium and the complexities in the dynamics of the underlying network.

MIMO-OFDM is a key technology for next-generation cellular COMMUNICATIONs (3GPP-LTE,
Mobile WiMAX, IMT-Advanced) as well as wireless LAN (IEEE 802.11a, IEEE 802.11n),
wireless PAN (MB-OFDM), and broadcasting (DAB, DVB, DMB). This book provides a
comprehensive introduction to the basic theory and practice of wireless channel modeling,
OFDM, and MIMO, with MATLAB ? programs to simulate the underlying techniques on
MIMO-OFDMsystems.Thisbookisprimarilydesignedforengineersandresearcherswhoare
interested in learning various MIMO-OFDM techniques and applying them to wireless
COMMUNICATIONs.

There are few technologies that have had a more profound effect on people’s lives
than mobile COMMUNICATIONs. As recently as twenty years ago no one had a mobile
phone, while today 1.4 billion men, women and children depend on them. This now
exceeds the number of landline users, where it took the preceding one hundred years
to reach the 1 billion mark. The ability to make mobile voice calls turns out to be the
answer to a deeply felt need across different cultures who simply want to
communicate.

By definition, the term “mobile-radio COMMUNICATIONs” describes any
radio communication link between two terminals of which one or both
are in motion or halted at unspecified locations and of which one may
actually be a fixed terminal such as a base station. This definition
applies to both mobile-to-mobile and mobile-to-fixed radio communica-
tion links. The mobile-to-mobile link could in fact consist of a mobile-
to-fixed-to-mobile radio communication link.The term “mobile” applies
to land vehicles, ships at sea, aircraft, and COMMUNICATIONs satellites.
In tactical situations, mobile-radio systems may include any or all of
these types of mobile terminals.

Multi-carrier modulation? Orthogonal Frequency Division Multi-
plexing (OFDM) particularly? has been successfully applied to
a wide variety of digital COMMUNICATIONs applications over the past
several years. Although OFDM has been chosen as the physical layer
standard for a diversity of important systems? the theory? algorithms?
and implementation techniques remain subjects of current interest.
This is clear from the high volume of papers appearing in technical
journals and conferences.

This book focuses on the study and development of one of the most
advanced topics in broadband wireless COMMUNICATIONs systems:
power efficiency and power consumption in wireless COMMUNICATIONs
systems, especially of mobile devices. Hence, the main focus of this
book is on the most recent techniques for the conservation of power
and increase in power efficiency.

If you would like to follow along with some of the steps outlined in this book, we recommend that you
deploy Live COMMUNICATIONs Server 2005 SP1 on a physical or virtual server running Microsoft
Windows Server 2003. To run Communicator 2005, you will need a physical or virtual PC running
Windows XP or Windows Server 2003. To fully test Microsoft Office integration with Communicator
2005, you need to be running Microsoft Office 2003 with Service Pack 2.
