Comparison of Non-Cooperative Spectrum Sensing Techniques in Cognitive Radio

Kuldeep Kumar, Vikas Sindhu

Abstract


Cognitive radio is believed to be the future wireless communication system. Since in existing wireless communication system, static allocation of spectrum is used and that led to the problem called spectrum scarcity, the concept of cognitive radio was proposed by the Mitola in 1998. Spectrum sensing is an important and challenging issue in CR. Spectrum sensing is the detection of the primary user transmission in the allocated licensed spectrum band. In this paper different non-cooperative spectrum sensing and their comparison is shown.
