Spectrum Reuse in Multiple Primary User Environment

AR.Arunachalam

Wireless network represents an efficient technology as is allows exploiting the unused radio resources as it allows exploiting the unused radio resources. It allows secondary users to opportunistically access spectrum licensed by primary users, while protecting PU activity. Spectrum sensing plays an important role in Wireless networks communication. Spectrum sensing is the key enabling technology for Wireless networks. The main objective of spectrum sensing is to provide more spectrum access opportunities to Wireless networks users without interfering with the operations of the licensed network. Hence, recent research has been focused on the interference avoidance problem.
