The spectrum sensing is the base line on which the whole process of cognitive radio works. It has raised new facets for cognitive radio and many opportunistic spectrum access approaches. To avoid the interference with the licensed users and determining the accessible spectrum for increasing the spectrum's usage is its pivotal task of cognitive radio. Generally, detection performance is compromised with receiver uncertainty, multipath fading and shadowing issues and an effective method to alleviate the effect of these issues is the cooperative spectrum sensing.
