A valuable addition to the Wiley Series in Microwave and Optical
Engineering
Today’s modern wireless mobile communications depend on adaptive
‘smart’ antennas to provide maximum range and clarity. With the
recent explosive growth of wireless applications, smart antenna
technology has achieved widespread commercial and military
applications.
The only book available on the topic of adaptive antennas using
digital technology, this text reflects the latest developments in
smart antenna technology and offers timely information on
fundamentals, as well as new adaptive techniques developed by the
authors. Coupling electromagnetic aspects of antenna design with
signal processing techniques designed to promote accurate and
efficient information exchange, the text presents various
mechanisms for characterizing signal-path loss associated with
signal propagation, particularly for mobile wireless communications
systems based on such techniques as joint space-frequency adaptive
processing.
In clear, accessible language, the authors:
* explain the difference between adaptive antennas and adaptive
signal processing
* Illustrate the procedures for adaptive processing using directive
elements in a conformal array
* clarify multistage analysis procedure which combines
electromagnetic analysis with signal processing
* present a survey of the various models for characterizing radio
wave propagation in urban and rural environments
* describe a method wherein it is possible to identify and
eliminate multipath without spatial diversity
* optimize the location of base stations in a complex
environment
The text is an excellent resource for researchers and engineers
working in electromagnetics and signal processing who deal with
performance improvement of adaptive techniques, as well as those
who are concerned with the characterization of propagation channels
and applications of airborne phased arrays.
