ABSTRACT

Cognitive radio is the emerging technique which can be used in wireless communication systems. This technique is utilized to expand the spectrum usage productively. In the process of effective utilization of spectrum, the main component used by cognitive radio is spectrum sensing technique. Since, maximum spectrum is assigned to primary users and it is under utilized hence, efficient utilization of spectrum is an essential issue. The unused band of primary users can be assigned for reuse to supply broadband network services without any interference. In our paper, energy detection concept is used to perceive the unused bands of the spectrum and make them available for the reuse purposes. With this concept we can determine the white spaces in the spectrum and assign to secondary users.
