A complete discussion of MIMO communications, from theory to real-world
The emerging wireless technology Wideband Multiple-Input, Multiple-Output
(MIMO) holds the promise of greater bandwidth efficiency and wireless link
reliability. This technology is just now being implemented into hardware and
working its way into wireless standards such as the ubiquitous 802.11g, as well
as third- and fourth-generation cellular standards.
Multiple-Input Multiple-Output Channel Models uniquely brings together the
theoretical and practical aspects of MIMO communications, revealing how these
systems use their multipath diversity to increase channel capacity. It gives
the reader a clear understanding of the underlying propagation mechanisms in
the wideband MIMO channel, which is fundamental to the development of
communication algorithms, signaling strategies, and transceiver design for MIMO
MIMO channel models are important tools in understanding the potential gains
of a MIMO system. This book discusses two types of wideband MIMO models in
detail: correlative channel modelsspecifically the Kronecker, Weichselberger,
and structured modelsand cluster models, including Saleh-Valenzuela, European
Cooperation in the field of Scientific and Technical Research (COST) 273, and
Random Cluster models. From simple to complex, the reader will understand the
models' mechanisms and the reasons behind the parameters. Next, channel
sounding is explained in detail, presenting the theory behind a few channel
sounding techniques used to sound narrowband and wideband channels. The
technique of digital matched filtering is then examined and, using real-life
data, is shown to provide very accurate estimates of channel gains. The book
concludes with a performance analysis of the structured and Kronecker models.
Multiple-Input Multiple-Output Channel Models is the first book to apply
tensor calculus to the problem of wideband MIMO channel modeling. Each chapter
features a list of important references, including core literary references,
Matlab implementations of key models, and the location of databases that can be
used to help in the development of new models or communication algorithms.
Engineers who are working in the development of telecommunications systems will
find this resource invaluable, as will researchers and students at the graduate
or post-graduate level.
