A valuable addition to the Wiley Series in Microwave and OpticalEngineering
Today's modern wireless mobile communications depend on adaptive"smart" antennas to provide maximum range and clarity. With therecent explosive growth of wireless applications, smart antennatechnology has achieved widespread commercial and militaryapplications.
The only book available on the topic of adaptive antennas usingdigital technology, this text reflects the latest developments insmart antenna technology and offers timely information onfundamentals, as well as new adaptive techniques developed by theauthors. Coupling electromagnetic aspects of antenna design withsignal processing techniques designed to promote accurate andefficient information exchange, the text presents variousmechanisms for characterizing signal-path loss associated withsignal propagation, particularly for mobile wireless communicationssystems based on such techniques as joint space-frequency adaptiveprocessing.
In clear, accessible language, the authors:
* explain the difference between adaptive antennas and adaptivesignal processing
* Illustrate the procedures for adaptive processing using directiveelements in a conformal array
* clarify multistage analysis procedure which combineselectromagnetic analysis with signal processing
* present a survey of the various models for characterizing radiowave propagation in urban and rural environments
* describe a method wherein it is possible to identify andeliminate multipath without spatial diversity
* optimize the location of base stations in a complexenvironment
The text is an excellent resource for researchers and engineersworking in electromagnetics and signal processing who deal withperformance improvement of adaptive techniques, as well as thosewho are concerned with the characterization of propagation channelsand applications of airborne phased arrays.
