Abstract: As the field of wireless communication is growing very rapidly in last ten years, the problem of bandwidth scarcity is also increasing and has become more hectic day by day. On the other hand, the studies made by Federal Communications Commission showed that large portion of the spectrum lies vacant most of the time and that portion is the licensed spectrum band; which is utilized by licensed users only. So, to solve this problem of spectrum under-utilization, Federal Communications Commission allowed secondary users to utilize the licensed band when it is not in use and named it as Cognitive Radio. To solve the spectrum overcrowding problem, cognitive radio (CR) has emerged as a leading technology because it can intelligently sense an unused spectrum and allocate it to the secondary users without creating any harm to authorized users.
