Thanks to this very flexible approach, any order of differential arrays can be designed. Moreover, they can be made robust against white noise amplification, which is the main inconvenience in these types of arrays. The other well-known problem with linear arrays is that electronic steering is not really feasible.  In this book, we extend all these fundamental ideas to circular microphone arrays and show that we can design small and compact differential arrays of any order that can be electronically steered in many different directions and offer a good degree of control of the white noise amplification problem, high directional gain, and frequency-independent response. We also present a number of practical examples, demonstrating that differential beamforming with circular microphone arrays is likely one of the best candidates for applications involving speech enhancement (i.e., noise reduction and dereverberation). Nearly all of the material presented is new and will be of great interest to engineers, students, and researchers working with microphone arrays and their applications in all types of telecommunications, security and surveillance contexts. 410 0$aSpringer Topics in Signal Processing,$x1866-2617 ;$v12 606 $aSignal processing 606 $aTelecommunication 606 $aSignal, Speech and Image Processing 606 $aCommunications Engineering, Networks 615 0$aSignal processing. 615 0$aTelecommunication. 615 14$aSignal, Speech and Image Processing. 615 24$aCommunications Engineering, Networks. 676 $a620 676 $a621.382 700 $aBenesty$b Jacob$4aut$4http://id.loc.gov/vocabulary/relators/aut$0721063 702 $aChen$b J$g(Jingdong),$4aut$4http://id.loc.gov/vocabulary/relators/aut 702 $aCohen$b Israel$c(Professor of electrical engineering)$4aut$4http://id.loc.gov/vocabulary/relators/aut 906 $aBOOK 912 $a9910299681803321 996 $aDesign of Circular Differential Microphone Arrays$92542721 997 $aUNINA
