Abstract

Cognitive radio (CR) is the enabling system for sustaining dynamic spectrum admittance: the policy that addresses the spectrum shortage difficulty that is encountered in many countries. The spectrum sensing trouble has gained new features with cognitive radio networks. Radio spectrum is the most expensive reserve in wireless communication. The cognitive radio and cognitive based networking are transforming the fixed spectrum allocation based communication systems in to dynamic spectrum allocation. Cognitive radios are smart devices with ability to detect environmental situations and can change its factors according to the necessity to get the optimized performance at the individual nodes or at network level Thus, CR is widely regarded as one of the most talented technologies for future wireless communications.
