Abstract—Spectrum Sensing is the most crucial task in Cognitive Radio Networks (CRN). The role of
Secondary User (SU) is to sense the spectrum continuously and detect whether the Primary
User (PU) signal is present or absent. The detection performance in practice is often
compromised with multipath fading, shadowing and receiver uncertainty issues. To address
these issues Cooperative Spectrum Sensing (CSS) is used. Cooperation among multiple
secondary users can be utilized to improve the sensing performance and increase the efficiency
to detect spectrum holes in CRN. In this paper we present the classification of Cooperative
sensing approaches and fusion schemes used in CRN. A comparison of those approaches and
schemes is also presented in this paper.
