You find expert guidance in the key enablers with respect to communications and signal processing. The book presents fundamentals, basic solutions, detailed discussions of important enabler issues, and advanced algorithms to save you time with your projects in the field. For the first time in any book, you find an adequately detailed treatment of spectrum sensing that covers nearly every aspect of the subject. Moreover, this valuable resource provides you with thorough working knowledge of localization and interference mitigation as enablers of cognitive radio technology. The book includes all the necessary mathematics, statistical and probabilistic treatments, and performance analysis to give you a comprehensive understanding of the material.$cPublisher abstract. 410 0$aArtech House mobile communications library. 606 $aCognitive radio networks 615 0$aCognitive radio networks. 676 $a395 700 $aSithamparanathan$b Kandeepan$01596863 701 $aGiorgetti$b Andrea$01596864 801 0$bCaBNVSL 801 1$bCaBNVSL 801 2$bCaBNVSL 906 $aBOOK 912 $a9910812094103321 996 $aCognitive radio techniques$93918394 997 $aUNINA
