Cognitive radio (CR) is a kind of wireless communication wherein a transceiver can intelligently sense the vacant and occupied communication channels and promptly move into vacant channels while staving off occupied ones. This enables the optimum use of available Radio-Frequency (RF) spectrum whereas avoiding the interference to other users. Cognitive radio is a key technology that came up with the solution of the problem of underutilization of radio frequency. To explore the capabilities and benefits of CR in better way, researchers now a days are interested in adaptive control paradigms such as fuzzy logic, artificial neural networks, neuro-fuzzy approach etc. The work presented in this book mainly composed of the analysis of available frequency and its allocation to the Secondary Users (SUs) / CRs by using fuzzy logic. A new approach of Spectrum management is introduced in it by resolving the issue regarding the allocation of bandwidth to the appropriate secondary user or the...
