Spectrum sensing Techniques In Cognitive Radio

The growing insist of wireless applications has put a lot of constraint on the usage of available radio spectrum which is limited and valuable resource. However, a fixed spectrum assignment has lead to under utilization of spectrum as a great segment of licensed spectrum is not effectively utilized. Cognitive radio is a promising technology which provides a novel way to improve utilizati helps to detect the spectrum holes (underutilized bands of the spectrum) providing high spectral resolution capability. In this paper, analysis of spectrum sensing techniques is obtainab in implementation of spectrum sensing techniques are discussed in detail giving comparative study of diverse methodologies
