Opportunistic Spectrum Access: An Overview,ncreasing demand for wireless communication applications on one hand and the success of wireless technologies in unlicensed spectrum bands on the other hand motivate the idea of opportunistic spectrum access (OSA). To enable OSA, cognitive medium access control (MAC) designs are required with intell
