In today times, the use of wireless communication increases rapidly. For a wireless communication, the radio spectrum remains constant but the user's increases very fast. According to Federal communication commission (FCC) research report, seventy percent of radio spectrum allocated has been already underutilized. So we want to overcome this problem by using some new technique. Cognitive Radio is a one of the method that will solve this problem. The rapid development in wireless services caused spectrum shortage. Cognitive Radio is a technique which uses licensed spectrum in a very efficient way.
