Cognitive radio (CR) is the idea of wireless architecture which doesn’t have a fixed operation frequency band. CR system searches the unused frequency spectrum and uses them to solve the problem of spectrum scarcity and meet the demand of more communication device. Here we discussed the various techniques for the spectrum sensing which made it

Nowadays, with the development of high data transmission service such as Internet and multimedia, the demands for high speed wireless access have been rapidly increasing. However, high speed communication has two severe challenges in wireless communication environment: one is how to improve the bandwidth efficiency of limited radio spectrum; and the other is how to
