In this paper, we analyze performance of spectrum sensing in unsynchronous cognitive radio network. When secondary network is unsynchronous with primary network, sensing probability decreases because of a synch error, miss detection probability and false alarm probability is derived by using central limit theorem. In simulation results, it is shown that in the unsynchronous network, false alarm probability increases very high for target miss detection probability compare to that in the synchronous network.
