摘要：The increased demand of services and applications on the wireless communication networks in thefuture requires wider ranges of spectrum. This enforces the designers to develop new techniques and solutions to usethe scarce spectrum efficiently. One of the proposed solutions is moving to new higher frequencies, but it is observedthat the licensed spectrum is not completely used where some parts are unused and others are not utilized. Cognitiveradio is an intelligent technique used in wireless networks to take advantage of unused or underutilized spectrum. Thismay be performed by allocating secondary users in the spectrum holes in order to enhance the efficiency of radioresource allocations.In this paper; spectrum sensing methods and secondary user allocation are performed to utilize the spectrum holes.The simulation Model is carried out using Matlab simulation program in order to study the performance of theproposed cognitive radio system.
