Abstract

To meet the increasing demand of applications in wireless networks, a wide range of spectrum is required. Cognitive radio is an intelligent loom to improve the spectrum utilization in an efficient manner. The main technology behind CR is spectrum sensing that identifies the vacant holes and to allot the vacant holes for the secondary users inorder to boost the allocation efficiency of radio resource. A survey of spectrum sensing methodologies used in CR is described in this paper. This paper also deals with the design and development of a technique to analyze and correlate spectrum allocation of secondary users using optimization problem of linear cooperative spectrum sensing techniques. The simulation tool used is Matlab, to learn the working performance of the proposed cognitive radio system.
