PrinciplesofCognitiveRadio
Widely regarded as one of the most promising emerging technologies for driving the
future development of wireless communications, cognitive radio has the potential to
mitigatetheproblemofincreasingradiospectrumscarcitythroughdynamicspectrum
allocation.

tion,optimization,andsignalprocessing,ateamofleadingexpertspresentasystematic

“This is the first book to cover the topic of cognitive radio from a fundamental view-
point.Itprovidesnewinsightsonpropagation,spectrumsensing,systemoptimization

“Muchhasbeenwrittenontheever-expandingsubjectofcognitiveradio.Thenewbook
entitled “Principles of Cognitive Radio”, written by well-respected authorities, fills a
gap by presenting detailed discussions of different aspects of this fascinating subject.
I recommend the book for use by researchers who are already working in cognitive
radioorplanningtomoveintoit.”

“PrinciplesofCognitiveRadio”isacomprehensivetreatmentofmanyofthefundamen-
tal issues that will impact cognitive wireless communications networks of the future.
The authors have done an excellent job bringing together many modern concepts that
are at the forefront of wireless, while reviewing the fundamentals along the way. As
aresult,theauthorshavecreatedanexcellentreferencetext,bringingawiderangeof
