Cognitive radio (CR) targets to make quick use of the radio spectrum that is currently limited. To support this characteristic, the secondary users are compulsory to experience the radio frequency environment once the primary person is discovered to be active the secondary users should get rid of the channel inside sure quantity of time. Sensing is a compelling identification technique for improving unearthly usage consequences of optional clients (SU) at nearly a similar time as holding essential clients. Throughput may be enhanced with the aid of choosing sensing time and the number of users Spectrum sensing is fundamental to identify spectrum holes. Cooperative spectrum sensing could really eliminate the problem of thoroughly corrupt detection by trying to exploit the spatial wider range embedded to lessen the possibility of being developed with primary user. The suitable sensing time and the appropriate number of users, designing appropriate fusion rule at the fusion middle. The results of the simulation affirm that throughput can be enhanced via selecting the best sensing time, the suitable quantity of SU's proper fusion rule and the proper frame period. By means of deciding on the appropriate sensing time and the proper quantity of users, the CR throughput may be more suitable.
